THE
DEAN'S OFFICE Parents and prospective students often ask whether USU, as a PhD-granting research institution, acknowledges and values undergraduate education. In reply, we.point out that our faculty are dedicated teachers as well as researchers and that three of our six departments in the College of Science have, to date, been recognized with the university's Dean Don Fiesinger Departmental Teaching Excellence awards. In addition, the College of Science has placed considerable emphasis on involving undergraduates in our research endeavors. This is reflected in our college motto: "When studentsand faculty learn together... ,

Within this current issue of Insights,we are highlighting the research efforts of our students and faculty and you will note that many of the students featured are undergraduates. From the Dean's office alone, we disperse nearly $100,000 each year in support of undergraduate research. For example, we offer College of Science Mini-grants of $1,000 for small, semester-long projects, and Willard L. Eccles Undergraduate Research Fellowships of $7,500 for year-long projects under the supervision of a faculty mentor. As many as 18 mini-grants and ten Eccles fellowships are awarded each year, with three mini-grants and at least one fellowship committed to majors in each of our six departments in the College. You will find mention of this support in various articles within this issue. This will be my last contribution to Insightsas Dean. Later this summer I will return to the Geology Department and resume teaching in the fall. I would like to take this opportunity to thank you, our alumni and other friends of the College of Science, for your continued support of our students, faculty, and academic programs. Our success is a reflection of your commitment to Utah State University. I anticipate even greater accomplishments among our students and faculty as we proceed under the strong leadership of our new dean, Dr. Mary Hubbard.Dr. Hubbard will leave her position as head of the Geology Department at Kansas State University and begin her duties as dean of the College of Science in July. Please give her a warm Aggie welcome.

Among the path planning algorithms proposed for use in ANS is a relatively new sampling-based method called Rapidlyexploring Random Leafy Tree. "RRLT has some advantages over older methods but it still has constraints, " says Watson, associate professor in USU's Computer Science Department. "There are characteristics of the RRLT approach that don't lend themselves well to a distributed approach - that is, having many agents working together to solve a problem ." A possible solution?

ls it the most thorough approach to path planning? Maybe not. But if you know the general direction you're heading, grabbing the nearest vine might get you in touch with Jane, Boy and Cheetah more quickly than stopping to ask for directions. That's the gist of an algorithm Computer Science undergraduate Arthur Mahoney is developing with faculty mentor Dan Watson. The two computer scientists are seeking a method to improve communications among agents - such as robots or a collection of processors - operating in a large network.
"Art (Mahoney) has taken the idea of RRLT and tried to come up with a way to randomly sample points in the domain - that is, randomly sample different vines in the jungle and add new vines until agents are found, " he says. "He calls this method 'The Nearsighted Tarzan Algorithm."' With just one year of college behind him, Mahoney, an Undergraduate Research Fellow in computer science, presented his and Watson's findings last summer at the 2006 International Conference on Parallel and Distributed Processing, Techniques and Applications in Las Vegas. "We got really good feedback," says Mahoney. "It was a great experience." "Conferences are a wonderful way to have your results reviewed by peers and get new ideas," says Watson. "One of the nice things is that our work will be read by other researchers in this field of study." Working on your own research project is much more meaningful than learning facts in the classroom, says Mahoney. "With my research
"Our focus is on communications in Altruistically Negotiating Systems or 'ANS,"' says Mahoney, who graduated from Utah's Logan High School in 2005. ANS, he says, feature a collection of agents with diverse responsibilities that behave in a manner in the best interest of the entire team. Sounds like a coach or military commander 's dream team, right? Well, yes, says Mahoney, but imagine that each visually challenged team member is working in a vast, fast-changing environment filled with hostile obstacles and doesn't even know if the other members exist. How do team members communicate with each other? One of the most common forms of ANS is Unmanned Autonomous Vehicle systems, which extend the reach of humans into dangerous environments and are increasingly used in industrial and military applications. "With UAVs, you have a group of robots equipped only with line-of-sight radio communications," says Mahoney. "Those communications are frequently interrupted by physical obstacles."

I've been forced to solve or work around problems that I would have never dealt with in class- and that's real computer science." Mahoney, who was recently named a 2007 Goldwater Scholar, is a 2006-07 Governor's Scholar, and a 2007-08 recipient of a Willard L. Eccles Undergraduate Fellowship, also thinks research makes learning more enjoyable. "Programming for a professor's homework assignments during the wee hours of the morning is tedious, stressful and bothersome - but programming for research during the wee hours is fun," he says. "Arr quickly learned the protocol for tapping into the university's undergraduate research opportunities and hit the ground running with this project," says Watson. "For students with initiative, there's a path for exciting hands-on learning at USU. There's definitely a path."

will be exposed to temperatures in excess of 1,400 K (1,700 degrees C or 3,400 degrees F), along with large fluxes of light and charged particles from solar wind. "NASA is trying to determine what materials could survive such a mission," says Albretsen, an Undergraduate Research Fellow who is completing her second year at Utah State. She was recently named a 2007 Goldwater Scholar and a 2006-07 Governor's Scholar. Working with mentors J.R. Dennison, Physics Department professor, and graduate student Ryan Hoffmann in USU's Materials Physics group, Albretsen subjects insulating ceramic materials, including aluminum oxide, barium zirconium phosphate and polyboron nitrate, to specific frequencies of light and measures the resultant current from electrons emitted by each material. "We place samples in a vacuum chamber," she says, indicating a large, round device that looks like a deep sea diving bell. "When light interacts with a surface, its energy is transmitted to embedded electrons. Often this forces the electrons out of the material, causing it to become charged. "

hen Daedalus constructed wings for himself and son Icarus to make their daring escape, his choice of materials was limited. And he knew the inherent risks of flying an apparatus crafted with wax too close to the sun.
In addition to the Solar Probe, which Hoffmann says resembles "a giant flying ice cream cone," the research trio and colleagues are investigating materials to construct NASA's James Webb Telescope, planned successor to the Hubble.
Physics undergraduate Jennifer Albretsen has a much broader and sophisticated range of materials to choose from for NASA's planned Solar Probe satellite, bur her concern still centers on the impact of solar radiation. And whereas Daedalus was preparing for low altitude flight and a comparatively short hop from Crete to Sicily, the Solar Probe is expected to travel within three solar radii (3 RS) of the sun's surface.

A Wisconsin native, Albretsen , a National Merit Scholar, USU Presidential Scholar and Honors Fellow, chose Utah State because "I felt welcome, not like a number." "USU was small enough that I felt like I would receive personalized attention, yet large enough to provide interesting research opportunities, " she says. Albrersen is enthusiastic about rhe projects that have come her way. "First of all, research is fun - it's a different experience from sitting in a classroom," she says. "You get a deeper understanding than from reading a textbook or doing homework. " Dennison concurs. "Undergraduate research is incredibly valuable because it gives students a chance to see what they can accomplish with what they learn from books, " he says. "C lasses are essential, but what makes science science is the thought process that goes with testing a hypothe sis. You have to figure our what you don 't know. There's no substirure for getting in the lab and making a lot of mistakes. "

also sees the value of undergraduate research. "Unlike many colleges, USU
offers many hands-on learning opportunities ," he says. "Not being involved in research is like going to a lecture about flying a plane without ever getting to pilot it. " He adds that as undergrads are added to the research group , he benefits from the teaching experiences. "For me, bringing new scientists up to speed makes the whole process much clearer in my mind, " he says. "Going back and explaining the basics keeps me focused on the big picture and helps me avoid getting caught up in details." Dennison says pairing undergrads with graduate students, as well as faculty mentors, provides the former with a valuable orientation for graduate school. "From the start of their college years, students are introduced to the opportunities offered beyond undergraduate study."

uring a virulent outbreak of cholera in mid-19th century London , physician John Snow doggedly went from door to door interviewing families of victims and piecing together evidence of disease transmission through contaminated water systems. With his collected data, Snow made a spot map that revealed the spatial distribution of cholera deaths - most clustered around a water pump in Soho's Broad Street.

In a study funded by the National Science Foundation and the U.S. Geological Survey, Hooten and co-investigators Christopher Wikle of the University of Missouri-Columbia and USGS scientists Robert Dorazio and Andrew Royle used a hierarchical Bayesian framework to explore the march of the Eurasian Collared-Dove (ECO) westward from Florida , its probable point of entry . The innocuous-looking gray bird, with a black half-collar at its nape , is now at mid-invasion, says Hooten. "ECO is a prolific species and may pose a threat to native ecosystems. We predict the bird will colonize the entire United States witl1in a few decades. " He notes that the dove is even taking up residence in USU 's community. "Based on model predictions, we are on the cusp of a very rapid period of ECO population growth here in Logan. "
Statistician Mevin Hooten
Snow's ideas were largely dismissed by the medical establishment of the time, which was mostly ignorant of microbiology and stubbornly clung to miasma theory. But his work paved the way for modern epidemiology and use of spatial and spatio-temporal statistics to test dispersal theories of natural phenomena . "These fields have burgeoned over the last few decades, " says USU statistician Mevin Hooten, who uses hierarchical models to determine how invasive species and diseases spread and change over time and space. While knowledge of germ theory and the sophistication of tools for statistical analysis have grown markedly , he says, the threat of modern pandemics - bird Bu, SARS - and the unknown consequences of invasive species foster as much fear and uncertainty as plagues of yore.
For Hooten and crew, the dove, disparaged by birders with such unflattering names as "scuzdove" and "Eurotrash," offered a ready opportunity for testing the efficacy of their modeling methods. "Large scale ecological datasets that provide quantitative population information are rare," he says. "Fortunately, the longterm monitoring efforts of the North American Breeding Bird Survey provided us with invasive species data to fuel our research. " The advantage of his team's method over other invasive species models, says Hooten, is its simplicity and flexibility. "It accommodates uncertainty and also provides tangible graphical and numerical output ," he says. "Ecologists and resource managers can use the results to understand ecological processes and make decisions. " â–

A forest ecologist by education and experience , Hooten, along with colleagues, recently applied emerging modeling methods to an invasive bird species gaining a foothold in North America. The team's research was highlighted in "HierarchicalSpatiotemporal Matrix Modelsfor CharacterizingInvasions," in the June 2007 issue of Biometrics. "The survival, interaction and spread of species are key elements of ecology," says Hooten , who joined USU 's Department of Mathematics and Statistics as an assistant professor in 2006 . "The statistics community has developed models to determine the abundance of species but we need better tools for understanding the actual population size of different species - particularly, invasive species."

his past spring semester, USU premedical, predental and prepharmacy students returned to grade school, with their sights se-ton getting into grad school. Forty Aggies assisted the Bear River Health Department and the University of Utah with a study aimed at determining whether short-term exposure to air pollution has a negative effect on the lung capacity of children, especially those with asthma. The study, which began January 8 and concluded March 8, was conducted with youngsters at North Logan's Greenville Elementary School. A Greenville Elementary student exhales into a spirometer. Photo by Eli Lucero, courtesy ofThe Herald Journal .
Clayton Cook, a sophomore predental student majoring in biology, said the study fulfills the requirement for students going into medical fields to participate in hypothesis-based research, bur it is more fun than some of the other options.
"Instead of going and working with some inanimate object, you're working with kids, you're working with people and that's what I enjoy," Cook said. Using a device called a spirometer, which measures the air volume a person exhales, the USU student researchers examined whether short-term exposure to Cache Valley's notoriously dirty winter air had an impact on the lung capacity of 100 third-, fourth- and fifth-graders. The children were required to blow hard and fast for six seconds into the tube-like instrument on test days before and after recess. The spirometer measured their lungs' forced vital capacity, and results were transferred to a computer and charred into graphs. Cook said the purpose of the study is to determine whether the kids are being harmed by the air. "We're not hoping there are bad effects. We just want to see what the effects are. If we're just sending chem out every day and it's affecting them adversely then we're at fault," he said. Cook, who said even he has trouble blowing into the device for a full six seconds, said though the results aren't complete, there is a noticeable difference in some of the children. "You can definitely tell the difference between those kids that do

have asthma and those kids that don't," Cook said. "Bur whether chat's because of the air quality, we don't know yet." Joseph Whitehead, a junior predental student majoring in biochemistry, said even though the study isn't directly related to dentistry, he believes his participation in it will help him get into dental school and later help him work with patients.
"This internship for me has been a good opportunity," said Whitehead. "It's the first time I've had any sort of patient exposure. We're always cracking jokes with the kids, ceasing them. I chink that exposure will help." Lane Severe, a junior predental student majoring in finance, said he also thinks the interaction with kids will help him lacer in his career. He said at first the children were timid but warmed up to the USU students once they began to get used to them and understand the study. Severe said, in dentistry, it's especially important to learn how to talk to kids in order to make them calm and comfortable .
"I've watched a few dentists and, you know kids get squirming around all over, and then you have to put a sharp thing in their mouth," he said. Severe said the research doesn't have to be related to dentistry to help him. He and his classmates have been able to interact with each other and with the children. He said because they're dealing with children, the students had to undergo fingerprinting and a background check in order to participate in the study.
TOWARD FEWER BAD AIR DAYS INVESTIGATINGTHECHEMISTRYOF POLLUTION USU analytical chemist Phil Silva is investigating the chemistry behind Cache Valley's problem air. The main source of the pollution, he says, comes out of the tailpipes of cars and cows. "Ammonium nitrate accounts for about 50 to 70 percent of northern Utah's air pollution," says Silva, an assistant professor in the Department of Chemistry and Biochemistry. "Ammonia is a byproduct of livestock waste. During inversions, our snow-covered valley allows ammonia to accumulate, which reacts with vehicle exhaust to form tiny ammonium nitrate particles."
Chemist Phil Silva
The unique landscape of Cache Valley, home of Utah State, makes it an enchanting place to live, study, work and play. Yet the encircling majestic peaks, the pastoral scenes of grazing cattle and the snowy winters are the very factors that contribute to one of the area's not-so-attractive qualities: hazy winter air pollution. During cold months, Logan and surrounding communities experience periods of air pollution caused by "inversions" or altitudinal increases in temperature. Stagnant high pressure systems trap cold air beneath warm air in bowl-shaped Cache Valley, which prevents pollutants from escaping.
"Most graduate schools are looking for anything that will set you apart from the next student, " he said. Physician Ed Redd, BRHD medical director, who is overseeing the study, praised the USU students, calling them "fantastic" and "dedicated." He said he believes their assistance in the study will help many of them get into graduate school. Overall, he said he has confidence in the USU students' understanding of the study and use of the spirometer, even though it's a "complicated piece of equipment ."
A rapidly expanding metropolitan region, Cache Valley has more than 85,000 registered vehicles and provides a busy travel corridor for freight and tourist traffic berween the southwestern U.S. and Rocky Mountain recreational areas. The area's robust dairy and meat industries boast upwards of75,000 head of cattle, 13,000 hogs and 4,000 sheep. In recent winters, Cache Valley has racked up unhealthy readings for PM2.5; that is, particles less than 1/40 the diameter of a human hair. Such readings are worrisome because the minute particles settle deep in the lungs and can cause health problems, says Silva, who serves as an advisor to the Bear River Health Department and the State of Utah's Division of Air Quality. Understanding the source of pollution, he says, is the first step toward formulating solutions. "Once we understand the causes, we can implement policies and provide information to the public so that everyone can do their part to lower pollution." â–
"He's teaching us a lot of the chemistry behind the inversion that happens in Cache Valley," Whitehead said. "The knowledge of that has been really cool, taking the things we learn about in class and applying them in real life." â–

n his writings and speeches, the late Kermit Hall, USU president from 2001-04, often referred to the distinct benchmark left by ancient Lake Bonneville char edges Utah State University's Logan campus. He used the landmark as a metaphor to describe-the university's strong foundation, crafted by efforrs of pioneering visionaries, and the institution's aspirations for continually higher standards of excellence. With the opening of the new USU Luminescence Laboratory on North Logan's Innovation Campus (formerly known as the USU Research Park), Aggies and local residents had the opportunity to learn more about the mysterious geological formations char lay beneath Utah's land-grant university. Managed by the Geology Department, the new lab features curring-edge capabilities in optically stimulated luminescence or "OSL" geochronology char enable geologists, archaeologists and ocher scientists to accurately determine the age of sediment samples. The lab's first assignment? How about determining the age of the USU campus? No, nor the date the university was established - which was 1888 - bur the actual age of the ground upon which Aggies walk.

In September 2005, a landslide overlooking Logan's Island neighborhood just south of the university quad exposed an inner USU research associate Gary O'Brien collects a sediment section of the sample from the site of the September 2005 landslide at the edge of Utah States campus . Lake Bonneville benchmark. While citizens and local authorities fretted about the mishap's implications for life, limb and property, USU geologists scrambled to collect precious samples.
Attendees of the lab's open house chis past January were invited to estimate the age of the lab's campus sediment samples and participants posed excellent guesses, says Pederson. "Ancient Lake Bonneville was around for a long time, so as we examine the deposits we have to ask, 'To what lake level stand do they belong?"' says Pederson. "And when did they occur during chat stand?" The lab's core instrument, which was funded by a grant from the Val A. Browning Foundation, is a luminescence reader developed by Denmark's renowned Ris0 National Laboratory. About the size of a personal computer, the reader uses controlled doses of radiation and light to incite and measure the responding light, or luminescent glow, of sand grains and thus determine their age. Pederson says recent technical advances in luminescence dating make it one of the most powerful, accurate and cost-effective methods for solving geological problems . It offers a number of advantages over conventional methods such as radiocarbon and cosmogenic dating of young geologic samples. Boch of these older methods are difficult and costly, he says, which means neither is conducive to student research.
''I'm always looking for ways to involve students in research," Pederson says. "T he new lab offers great opportunities for undergraduates and grad students to learn about luminescence dating and conduct projects on their own." Pederson says only a handful of similar labs are located in the United States. "T he U.S. is somewhat behind in this technology," he says. "More labs are currently found in Europe and India." Prior to the Utah State lab's opening, Pederson was sending samples from USU to out-of-state facilities. "I thought, 'Why use our precious research funding to send samples and students somewhere else when we could be doing the work here?'" He envisions the USU lab having a regional focus and primarily serving Intermountain students and scientists, though it already has clients in Thailand and Alaska. "We already have a six-month backlog in projects," he says. "The time and effort we devote to measurement of external samples will help fund the ongoing operations of the lab."

USU GEOLOGIST RECONSTRUCTS EVOLUTION OF MISSISSIPPI RIVER
OSL Lab Manager Tammy Rittenour Publishes Findings in GSA Bulletin Revered in song, literature and lore, the mighty Mississippi River pulses through the heart of North America on a long, winding amble. At first glance, Old Man River, aptly classified by scientists as a meandering river, reveals little of its distant past as a vast glacial stream. Yet recent findings by USU geologist Tammy Rittenour, bolstered with optically stimulated luminescence or "OSL" dating technology, support earlier speculation that glacial melt , not sea-level change, is largely responsible for the waterway's evolution during the past 100,000 years.

Other preparation includes involvement in extracurricular activities and undergraduate research, in which USU provides a wealth of opportunities. (Heffernan and colleagues were instrumental in recruiting prehealth majors to participate in rhe Bear River Health Department's study - see accompanying article in this issue.) USU grads also report that Biology lecturer Andy Anderson 's courses in human anatomy, physiology and dissection, as well as bioethics, put them well ahead of the pack in preparation for rough medical school courses. As students approach their junior year, rhe pressure's on. Aggies prepare for and complete the DAT or MCAT - professional school entrance exams - and begin the formal application process. The cost is steep. Students shell out roughly $3500 just ro apply and pay their own way to school interviews. The formal interview process begins during their senior year.

or an aspiring physician, dentist or other health care professional, preparations for post-undergraduate education begin long before commencement. Admittance to medical schools, dental schools and other health profession programs is highly competitive, yet USU graduates are consistently accepted at rates above the national average. Why? Much of the reason is due to the efforts of dedicated faculry and staff members who ensure that Aggies are well prepared for the application process.
F
"Ir's insane - the amount of work involved in preparing for and applying to (professional schools) is incredible, " says Liz Heffernan , prehealth advisor in USU's Biology Department. "That's why it's important to start early and begin with an organized plan." A common misconception people have about USU's premed program is that there's one set premed major or biology major, says Heffernan. "Wh ile it's true that certain courses are required for medical or dental school admittance, a prehealth student can choose to declare virtually any major."
Before heading to an interview, students benefit from a rigorous practice process, which includes mock interviews with three members from USU's Prehealth Professions Evaluation Committee. The 37-member, all volunteer committee consists of faculry and staff members from varied departments, along with local physicians and dentists. "We're very grateful to the generous people who volunteer their time to help our students pursue their goals," says Heffernan. "Our members try to simulate what a student will encounter in a real interview," she says. "Students get a lot of feedback on how ro make themselves more competitive." As students work toward their goal, Biology's Advising Center polishes applicants' letters of recommendation. "We prepare thorough, 3-page letters chat explain what makes chat person unique and why they're a strong applicant," Heffernan says. Throughout their undergraduate years, Heffernan encourages prehealth students to meet early and on a regular basis with both their prehealth and major advisors and to become involved in prehealth student groups. Her office also supports a peer advisor program, which offers extra support to students. Heffernan also urges students to attend prehealth orientation gatherings and to rake advantage of campus visits by representatives from professional schools. "We offer a lot of resources to those with initiative," she says.
In the Class of '07, 28 percent of the applicants to health profession schools were biology majors, but others pursued study in economics, English, nutrition , physics, Asian studies and a variery of other fields.
Heffernan says she's pleased that USU's Connections program's 2007 Summer Literature Experience, conducted by rhe Retention and First Year Experience office, will feature physician Atul Gawande's book, Complications: A Surgeon's Notes on an Imperfect Science.
"Today's professional schools are seeking students who are versed in a broad range of areas," says Heffernan.
"I think the book will be of great interest to our students," she says. â–

"Nathan is one of the best students I have seen in my 23 years at Utah State," Littlejohn says. "He is, for certain, going to one of the best graduate programs in the country."
The fellowship program was formally initiated by USU's Vice President for Research Office to identify ambitious students early in their college careers, guide them to faculty research mentors and provide them with a $1,000 stipend for research.
The Logan native plans to pursue studies at Princeton University following a two-year leave for humanitarian service.
Carruth graduated summa cum laude with a bachelor of science in mathematics and physics. Home schooled prior to college, he brought to USU 24 credits from Stanford University's continuing studies program in math. Carruth was mentored by Mathematics Professor Lance Littlejohn, who accompanied the undergrad to Europe to present a professional paper.
In addition to his undergraduate Nathan Carruth courses, Carruth undertook graduate study in physics. He was awarded an honorable mention in the National Science Foundation Graduate Fellowship competition. "Nathan advanced further and faster in his studies in physics than I could have imagined," says Physics Professor David Peak.

Each participant presents a lecture about his or her academic and professional jtmrney at university president Stan Albrecht's home during a reception attended by family, friends and colleagues. We congratulate the 2006-07 honorees -Adele Cutler, Mathematics and Statistics (who was featured in the Winter 2006 issue of Insights);Daryll DeWald, Biology; and Tim Gilbertson, Biology - who contribute immeasurably co our college.
It's About People Cell biologist Daryll DeWald loves to chase the big discoveries as much as the next scientist. Bue he concedes chat the human side of science is che most fascinating of all. "To loosely borrow Bill Clinton's 1996 campaign phrase, 'it'sabout people,Stupid,"' concludes De Wald. Head of the Biology Department, De Wald says he wanted his lecture "co celebrate the people I've interacted with" in an academic and professional journey chat's taken him throughout the United States. Noc chat De Wald has ever been a stranger co relocacion. A self-described Air Force brae, his family moved about every two years during his childhood. Each new home - in Texas, Louisiana, Colorado, Ohio, Okinawa, California - afforded varied environments for the budding scientist co explore . De Wald clearly remembers his fascination with ant lions in the Mojave Desert. The youngster scouted out the insects ' inverted cone-shaped homes and watched hapless ants cry co escape the traps of fine, slippery sand. "I called chem 'doodlebugs,"' he says.

Ac UW, De Wald met molecular biologist Randy Lewis, who became a significant mentor and friend. "We studie d endorphins and enkephalins - painkillers naturally produced by the bod y - and I had my first opportunity co publish my research," says De Wald. His own academic experience may explain why De Wald is a strong advocate for undergraduate research . "I have a real heart for undergrads, " he says. "Pai ring students with faculty mentors and involving chem in meaningful research is critical co a positive, produccive experience." Following graduation from UW, De Wald worked as an industrial scientist for pharmaceutical giant Upjohn. His areas of research included cancer biology and biopolymer chemistry. And coworkers approached him about being an alpha-tester for a promising new hair loss treatment. De Wald declined but recounts the memory with ironic amusement poincing to his own hirsutechallenged head. The resulting product was none ocher than bestseller Rogaine. De Wald headed back co academia and earned his doctorate in plant biochemistry from Texas A&M University. Postdoctoral studies followed at the prestigious Howard Hughes Medical Institute at the University of California, San Diego School of Medicine. He joined USU's faculty in 1995 and, prior co his appointment as Biology Department head in 2006, he served as associate director for research for USU's Center for Integrated BioSystems. De Wald's research interests span yeast, plant and mammalian cell signaling. "We're exploring what happens inside cells, how new proteins are made - protein trafficking, if you will."

"I don't see my role as just meddling about in a lab," he says. "I want to be doing things that help humankind."
In his pursuits, De Wald draws upon lessons learned from mentors, colleagues and students who have demonstrated strong moral positions. One of those mentors was his late father. "He invested in others, treated people with respect and valued them," says De Wald. "That 's the kind ofleadership model I try to emulate."
two choices: UC Davis and UC Irvine. "Honest to gosh, the truth is I couldn 't decide," he says. "It came down to a coin flip - UC Davis." Once ensconced in graduate study, Gilbertson made a very easy decision - to marry his newfound ultimate Frisbee partner, Donna. "She had only one condition and that was I had to promise never to live in a big ciry," he says.
Never Say Never Perhaps 'never say never' should be one of Tim Gilbertson's personal mantras . The Los Angeles native, who joined USU 's Biology Department faculty in 2000, was once "sure I'd be a lifelong Californian." After completing his undergraduate studies in biology and psychology at the University of California, San Diego, he also swore he'd never return to academia. "I was worn out from the tough, competitive grind, " Gilbertson says. He took a job as a research technician at The Scripps Research Institute by day and ran his own graphic arts business by night. What free time was left was devoted to surfing. Life was good, bur after a few years ofless-rhan-challenging assignments, Gilbertson decided it was time to head to graduate school. This rime, however, his interest, fueled by his sideline pursuits in graphic design, focused on a new area of study. Accepted into UC Berkeley's graduate program in architecture, Gilbertson started making moving plans. His boss at Scripps had very different plans. "Once he caught wind of my intent to leave biology, he convinced me to stay at least one more year - and upped my salary considerably." Gilbertson put Berkeley on hold and embarked on what would become his first foray into "actual research." Four years in college and several more at Scripps and no research experience? Nor really, says Gilbertson. "At that time, undergrads at UC San Diego basically washed dishes in the lab, and as a technician at Scripps I was helping other investigators," he says. "These are highly competitive environments." During his final year and a half at Scripps, Gilbertson says his supervisor "really took the time and effort to involve me in research and , during that rime, I ended up with eight publications. "
Another pivotal decision followed, when Gilbertson chose to change his research focus from highly studied visual systems - the eyes - to the relatively untouched study of taste systems. "I thought it would be a good move for a new investigator trying to find his niche," he says. The decision propelled Gilbertson and his new bride out of California , first to Colorado, then to Louisiana State Universiry's Pennington Biomedical Research Center. But in each instance, Gilbertson kept his promise of rural residences, affording the couple homes in the majestic beauty of Estes Park and the mossladen swamps of St. Amant. Now happily settled in Utah - Donna is an assistant professor in USU 's Psychology Department - Gilbertson continues his quest for answers to a question that dates back to his undergrad years, "How do cells work together to affect changes in behavior?"
In USU 's emergent Center for Advanced Nutrition, in which he works with his former LSU collaborator, USTAR professor David York, Gilbertson is exploring how our taste systems regulate our food choices. "With David (York) on board, I feel like my career has come full circle," he says. "The center is really getting its feet under it and we're starring to meet our objectives." â–

Melody Rose Anderson Spring '07 Valedictorian
Tackling complicated math and stats problems proved a formidable challenge for Carli Capener Potter, who earned a BS degree in composite mathematics/scaciscics education. But an even greater challenge was boosting the fragile confidence of students at Logan High School who were preparing to cake the state's basic mathematics competency test.
By the time she entered Utah's Copper Hills High School, Melody Anderson knew she wanted to become a high school teacher or a physician. Either profession, she thought, would allow her to "benefit people in a major way." With acceptances to five medical schools in hand, it appears Anderson is well on her way to a career in medicine.
Potter says she appreciated the collegial atmosphere among teachers at Logan High and was excited to be invited to assume teaching duties in early 2007 for a teacher going on maternity leave. "The teachers at Logan collaborate a lot and share materials and ideas," she says. "Even though I was a student teacher, they treated me as an equal and offered good advice." She now heads to a permanent teaching position in Utah's Box Elder School District, following in her grandfather's footsteps. Potter says she "always wanted to be a teacher" and, by middle school, she knew she wanted to be a math teacher. "I really liked math and took every math course I could in middle and high school," says the native of the tiny farming community of Riverside, Utah. She began her undergraduate career at BYU-Idaho in Rexburg, but chose to transfer to USU along with her husband, Justin Potter (BA 2006, English) in 2004. Interestingly, the pair grew up only two and half miles apart but didn't meet each other until about a year before their marriage. "The change to Utah Scacewas good," says Potter. "I got a great education at USU. I couldn't have asked for better. And I've loved going to Aggie basketball games." Potter was accompanied by faculty escort JimCangelosi, professor of mathematics, at Fall '06 Commencement. "Dr. Cangelosi was the first person I met at USU and has taught me so much about teaching," she says. "He's offered new perspectives and he's always been there for me."

Shortly before graduation, Anderson was awarded a Phi Kappa Phi Graduate Fellowship for 2006-07. She is one of only 57 recipients of the prestigious award nationwide and joins 12 Aggies who have won the fellowship since 1995. An Honors student, Anderson graduated with a 4.0 GPA in her biology major and chemistry minor, along with an impressive resume of research and service projects accomplished during her undergraduate career. A recipient of the Willard L. Eccles Undergraduate Research Fellowship, one of Melody's research ventures was investigating enhanced biological control of the Cereal Leaf beetle with faculty mentor Ted Evans. Anderson also served as an Undergraduate Teaching Fellow for human anatomy with faculty mentor Andy Anderson. The experience allowed her, she says, to "share my enjoyment of the subject with others." Teaching and research, she says, "cemented the information further in my mind and allowed me to apply and understand concepts from different angles." She invited Anderson to be her faculty escort at spring commencement. Beyond campus, Anderson maintained a busy volunteer schedule, serving as a hospital operating room volunteer, a tutor to elementary school students, a hospice volunteer and a volunteer intern in a pediatrics practice. During her USU career, Anderson managed to squeeze in an Aggie basketball game or two and enjoy the occasional mud football game or ultimate Frisbee match with roommates. She leaves USU with fond memories of"terrific academic opportunities on a research-oriented campus with great friends, fun times and beautiful mountains at our doorstep. "

Continued from page 11
Michael Blum, now of Louisiana State University, and Ronald Goble. In a paper published in the May-June 2007 issue of the GeologicalSocietyof America Bulletin, Rittenour's detailed examination of the river's fluvial evolution, conducted from the southern tip of Illinois co Baron Rouge, La., builds on findings from 20th century studies. The Mississippi River spawned from the waters of ancient Lake Agassiz, which domin ated present-day central Canada. Rittenour says the waterway has alternately changed from a braided river - featuring multiple, intertwined channels indicative of glacial runoff - co a meandering river in response co shifting glacial periods. Throughout much of the river valley, rhe landscape along the Mississippi appears almost flat. Bur satellite images reveal a web of braided belts throughout the river valley- remnants of glacial melt snaking its way south. "Our new chronology and longitudinal profiles of the Mississippi offer insights into rhe response of this continental-scale river system to climatic and sea level changes during the most recent glacial cycle," says Rittenour , who joined USU as a postdoc researcher in 2005. "T his could shed light on the future impact of climate events on the river." Rittenour spent four years collecting core samples from braid belts along the river and hauling them back to her alma mater's luminescence lab for processing. "It was kind of like following Huck Finn's path ," she says. "I encountered a lot of fried catfish and hush puppies on the menus of old cafes along the way." Rittenour was instrumental in the planning and installation of USU's new luminescence geochronology lab. "Lumi nescence dating offers a wealth of new research opportunities," she says. "The technology is powerful, accurate and cost-effective." Since joining USU, Rittenour notes that she now lives outside the massive Mississippi River watershed, which stretches from western Montana to Pennsylvania. Her focus now, she says, is working with colleagues on study of the American West's Colorado River. â–

In Tech, located on the university's Innovation Campus, first opened its doors to students in 2006. For the high school students, a day in the chem lab offered a glimpse of learning opportunities that await them at the university level. For members of the USU Chemistry Club, undergraduates who conducted the workshop for high schoolers, the gathering offered a valuable lesson in peer mentoring.

"O h, that 's disgusting!" exclaimed one participant as students watched a "carbon snake" - a gray mass formed from an organic compound mixed with sulfuric acid - slowly bulge from a beaker. "T he snake is a graphite form of carbon," USU undergrad Sara Huefner explained to the group. "It's one of the known 'allotropes' of carbon. Do you know what an allotrope is?" "Isn't it, like, when you have the same chemicals but in a different form?" ventured one student. "You are so correct!" answered Huefner. "Can anyone give me an example of another allotrope of carbon? I'll give you a hint - what's something really expensive you wear on your hand? "
"It lets the kids see that chemistry can be applied to everyday things," added Matthew Volle,a sophomore biochem major who also helped with the workshop. "Examples of chemistry are all around us." A veteran of four peer mentoring gatherings plus three demonstrations for Aggie Family Day, Volk is an old hand at engaging youngsters in learning activities. Huefner still has some doubts. 'T m a terrible mentor ," she lamented. "I have trouble keeping everyone on task." Maintaining focus and order among active teens, the mentors agreed, is a formidable challenge. But a worthwhile endeavor, Berreau, faculty advisor, assured the undergrads. "Inviting teens to campus is a key step in the recruitment process," she said. "We need to reach these kids early to spark their interest in science and let them know about the many opportunities that are available to chem."
"Diamonds!" the students chimed in unison. At another station, students stretched long, sticky strands of dissolving Styrofoam, in an experiment demonstrating what happens to polystyrene molecules when mixed with a solvent. "It looks like a promo from a Spider-Man movie," quipped USU Chemistry and Biochemistry Department Head Steve Scheiner. At yet another station, teens burst into giggles over white foam spewing from a flask. "You like to blow things up, I see," said Lisa Berreau, associate professor and associate dean of USU's College of Science. "Okay, that doesn't surprise me."
Berreau and other faculty members in the Department of Chemistry and Biochemistry will test the waters this summer with a week-long chemistry workshop for students from In Tech. Innovation funds awarded from the college's budget will cover the cost of this year's inaugural gathering. The goal is to expand the opportunity to students from other Utah high schools in coming years, she said. "Many teens simply don't know about all the learning and scholarship opportunities that USU offers," said Berreau. "Perhaps they haven't even considered that college is an option they can pursue . Our outreach programs, bolstered by our undergrad peer mentors, are an effort to change that. " â–

USU physics professor Mike Taylor looks beyond the Earth's visual atmosphere to the mesosphere, where the highest clouds, called noctilucent Mike Taylor or "night-shining" clouds - invisible during daylight - form at the edge of space. "The mesosphere is the coldest region in our solar system up to the orbit of Saturn," Taylor says. "Very little is known about the icy clouds that develop in this region." Taylor is a member ofNASA'.s science team for the Aeronomy of Ice in the Mesosphere or "AIM" mission, which successfully launched a spacecraft into orbit April 25. USU's Space Dynamics Laboratory designed and built one of the instruments that will fly on the spacecraft and collect information about how and why noccilucent clouds, also called polar mesospheric clouds or "PMCs," form. PMCs occur some 50 miles above the Earth's surface and are only visible at twilight, as the sun sinks below the horizon and illuminates the elusive formations. Historically seen only at higher latitudes, Taylor spotted the clouds from his ease bench Logan home back in the summer of 1999.

"I was sitting on the deck with my brother-in-law when I saw them and jumped up to grab a camera," says Taylor. "We ended up running about the neighborhood photographing the clouds with both scill and video cameras." Taylor's chance glimpse remains che lowest documented sighting of PMCs from the United Scares. Bue the frosty clouds are being seen more frequently at lower latitudes - farther from their polar homes - and they seem to be growing brighter and more numerous. Could they be yet another harbinger of global climate change? "We can't say for sure. We don't have enough information," says Taylor. "T har's one of the things AIM will help us study - we'll be examining links between lower and upper atmospheric phenomena." SDI.:s SOFIE, or Solar Occulcacion for Ice Experiment, instrument will measure a variety of atmospheric components, including temperature and water vapor, to probe the chemistry involved in forming the clouds, says Taylor. "We still don't know what makes up the clouds," says Taylor. "We know the ingredients, bur we don't yet have the recipe." He looks forward to traveling to Alaska this summer with a ream of USU undergrad researchers to sec up field data collection stations at two sites about 30 miles apart. "With the AIM spacecraft in orbit, we'll be able to collect data from both above and below the mesosphere," says Taylor. "T his will be a golden opportunity to learn more about these mysterious clouds ." The AIM mission is a poignant venture for Utah Scace.NASA granted SDL permission to include an engraving on the SOFIE instrument in memory of engineer Brandon Paulsen '97, '98MS. A USU graduate who began working at SDL while still a student, Paulsen, 32, managed the design of SOFIE prior to his death from cancer in 2005.

A
well-known student research team at USU-which is responsible for one of the university's well known bragging points - has taken on a new name , along with new challenges. Efforrs by the Get Away Special or "GAS" team have led to USU sending more student-built experiments into space than any other university in the world. The interdisciplinary MRT member Steve Berkley displays his papier-mache program, which model of the original Sputnik satellite. fuses students ' diverse interests and talents into exciting team-building ventures , is now called the Microgravity Research Team or "MRT." As NASA's mission evolves and private space endeavors increase, so too is MRT exploring new opportunities in space and atmospheric research, says student team member Steve Berkley. On MRT's agenda is the design and construction of "Little Nik" - USU's Sputnik CubeSat to commemorate the 50th anniversary of the first Sputnik space missions in 2007. Many alumni will recall chat Sputnik 1, the first artificial satellite, was successfully launched into orbit by the former Soviet Union on October 4, 1957. Sputnik 2, carrying Laika the dog, was launched on November 3, 1957.

In addition, the team continues working on microgravity research projects to be launched on NASA's K-Bird aircraft. The K-Bird is a specially outfitted C-9 military transport jet that dives from 30,000 to 20,000 feet in a controlled 25-second free fall to simulate weightlessness without leaving the earth's atmosphere. The plane has earned the moniker "Vomit Comet, " due to its potential impact on hapless passengers experiencing repeated shifts from minus-g to plus-g. STUDENT SPACE RESEARCH ... Continues on page 30
CHRISTMAS IN JULY Aggies Share 'Out of this World' Holiday Cheer Last December, it was beginning to look a lot like you-knowwhat with the usual lights, tinsel and ubiquitous candy canes adorning trees, storefronts and street corners. Bah, humbug! USU's Microgravity Research Team added some extraterrestrial pizza.zzto a Salt Lake tannenbaum to share Aggie-infused holiday cheer with a statewide audience. The team created an ornament for KSL-TV's Studio 5 Community Christmas Tree with a hint of space wonder. The decoration was constructed with parts from student-built experiments flown on past space shuttle missions. The Aggie-blue globe, which sported the university's wordmark and an orbiting satellite, was featured on the Studio 5 television program and remained on the program's community Christmas tree, a focal point for Studio 5 viewers, during the holiday season. ■
While Sputnik 1 was roughly the size of a basketball, Little Nik will fit into a box about the size of a softball. "Our plan is for Little Nik to broadcast Sputnik 's original signal, plus something about Utah State," says Berkley. MRT is also contributing to efforts to provide future lunar astronauts-NASA plans a four-astronaut moon landing in 2020-with the means to freely move about the moon's surface. Undergraduate Vicki Ragsdale says the team is investigating the use of magnetic energy to power future moon buggies. She adds that the lunar terrain poses significant challenges. "You've got to deal with dust on the moon, " she says.
