Improving the student experience
Responding to the changing needs of society
We aim to create the digitally literate workforce necessary for society’s future.
We are using our own campus, community and state to serve as real-time living laboratories for the development of new technologies. This includes the development of the iClassroom, a 21st century educational sandbox.
We are working to meet the demand for engineers by recruiting from a wider array of demographics and ages, providing them with skills and information as their careers require them
Dear UF BME Friends & Family, Welcome to the 6th issue of CrossLink, the annual magazine of the J. Crayton Pruitt Family Department of Biomedical Engineering at the University of Florida.
In this issue, we want to celebrate the innovative work being conducted by our women faculty and students and to highlight the importance of a diverse community. At a time when the opportunity could not be greater, women are vastly underrepresented in the workforce, particularly engineering careers. Our mission is to create an environment welcoming to all. The department’s goal is to continue to increase the recruitment, retention and graduation of students from underrepresented minority groups, and provide support for their inclusion and success in the academic environment. Changing culture is hard and without support from the top, almost impossible. Read about Dean Cammy Abernathy’s vision on page 8. Strategic hiring initiatives have enhanced the learning environment for students. Since 2013, we have recruited eight female faculty, increased women and underrepresented minorities in our students and hired 12 female personnel. In 2018 the department created the diversity and inclusion committee to continue to strengthen these engagements. You can read more about the fantastic leadership activities on pages 16 & 17. Although there is still much to accomplish and our journey is ongoing, I would like to share with you some best practices based on our experience thus far.
DIVERSITY BEST PRACTICES 1. Make diversity and inclusion a regular part of the conversation - leaders should emphasize the need for respect of all team members and the role everyone plays 2. Highlight the importance of a diverse team and support with data 3. When practical, put women and underrepresented minorities in positions that have an impact - empower and support them 4. Create a diversity officer and diversity organization provide them with a meaningful budget 5. Encourage and stress the need for balance and attention to mental and physical health 6. Recruit with the intent of recruiting a partner and family

BREAKING BARRIERS
Defining Leadership and Fostering Change
By Laura E. Mize
W
hen Dean Cammy Abernathy, Ph.D., hired Christine Schmidt, Ph.D., to lead the J. Crayton Pruitt Family Department of Biomedical Engineering in 2013, the new chair became the department’s third female faculty member at the time. There were 14 men. Abernathy’s selection was strategic. Schmidt’s research expertise in tissue engineering and her role in helping to establish biomedical engineering at the University of Texas, Austin made her an ideal candidate for developing the department. And as a woman, she fit well into the dean’s plan to diversify the college, from the top down.
Abernathy is especially fond of hiring or promoting highly qualified female and underrepresented minority candidates into key leadership positions, and asking them to make diversity a priority. “Nothing happens in a college unless the department chairs make it happen,” she said. Abernathy also emphasizes the importance of accountability in diverse hiring, of developing a college “climate” that’s welcoming to women and helps them succeed, and of including diversity metrics in rankings such as those published by U.S. News & World Report. 8 • FALL 2019
Employing these and other methods has indeed increased the number of female faculty members within UF’s Herbert Wertheim College of Engineering. In 2018, women made up 22 percent of the faculty, up from 10 percent when Abernathy became dean in 2009. Currently, 30 percent of faculty hired each year are women. Before Abernathy, that number was lower than 10 percent. But, there’s more work ahead. Her ambitions for greater inclusion of women in the faculty keep her working, still. Abernathy’s goal for the proportion of female faculty in the college is simple: She wants it to be 50-50.
Enticing Women to Stay While Abernathy has been working at the college level, Schmidt has been busy creating an atmosphere meant to support all the faculty in the J. Crayton Pruitt Family Department of Biomedical Engineering — with the belief that it will be especially helpful for women. She recognizes that having more women faculty requires a greater effort than just hiring women. The department’s representation of women among its faculty has improved to 10
in 25. Schmidt aims to make sure the women she has hired want to stay. Taking a “holistic view of our faculty,” one that encourages health and happiness in all areas of each employee’s life — not just in professional life — is critical, said Schmidt, who also serves as current president of the American Institute for Medical and Biological Engineering. “Our faculty are people with families, and if they’re successful in their home lives and their personal lives, they’re going to be much more successful at work,” she noted. Family-friendly practices are helpful for men, too, but “definitely much more imperative for my female faculty,” Schmidt said. Such practices include mostly restricting meetings to normal working hours in deference to childcare responsibilities, encouraging regular vacations and hosting workshops on work-life balance. In one-on-one meetings with faculty, discussions may turn to schedule or childcare difficulties. “Some of the time we’re just talking about things like nannies and daycares,” Schmidt said, noting that she is open about her own experiences juggling work and home life.
Dr. Aysegul Gunduz Dr. Cammy Abernathy

To further develop the growing climate of diversity and inclusion, Schmidt has established the new position of diversity officer within the department. Aysegul Gunduz, Ph.D., an associate professor, has taken on the role.
or they feel as if they’re not good enough to go to graduate school,” Stabler said. “And sometimes all it takes is just that personalized encouragement: ‘Yes, you do belong and this is the place for you.’”
Gunduz also is a past president of the Association of Academic Women at UF, and is involved with the department’s Diversity and Inclusion Initiative. She believes that biomedical engineering, as one of the youngest engineering fields, has an opportunity that other fields with an already-established “glass ceiling” don’t.
Acknowledging the program’s demanding nature is also important in helping students — especially women and minorities — feel connected and confident. Stabler cited studies showing that when a lecture “doesn’t make any sense, if you are an underrepresented minority or a woman, you tend to think, ‘I’m the only person in the room who doesn’t understand this,’” she said.
“This is a great chance for us to allow everyone to grow without any preconceived ideas about what a biomedical engineer should look like,” she noted. “So, we need female representation to attract others. The downside to being a young field is that the general public might not know what a biomedical engineer does. Hence, it is our responsibility to educate the public, so that young women can form a more accurate picture of biomedical engineers in their minds.”
Personalized Student Recruiting Attracting and retaining female graduate students takes work, too. Professor Cherie Stabler, Ph.D., recently ended her four-year term as the department’s associate chair for graduate education. In that role, she promoted what she calls “personalized recruiting.”
That perspective discourages students from asking questions. “You kind of isolate yourself because you feel like you’re the only one who doesn’t get it,” she explained. “Whereas the majorities in the room … tend to think, ‘If I don’t get it, nobody else does.’ And that means they build better peer networks.” These dynamics, Stabler said, make it important for faculty to relay to students that, yes, the program is tough, and it is OK if they don’t always understand the material. Personally addressing obstacles specific to women is helpful, too. Stabler uses student exit interviews to discuss workplace issues, including the importance of women “realizing their power,” and negotiating for favorable positions and salaries.
Often, prospective students, “especially women and underrepresented minorities, feel as if they don’t belong, CROSSLINK

Female Engineering Students
Department faculty take this approach beyond UF, as well. Lakiesha Williams, Ph.D., an associate professor, is a mentor with ACADEME. The workshop, which operates at a different campus each summer, coaches engineering postdocs and doctoral students who are women or members of other underrepresented groups, to help them jumpstart and succeed in academic careers.
Then:
Opening Doors For Everyone
THEN AND NOW The first woman to receive an engineering degree earned hers in 1876, according to the Society of Women Engineers (SWE). From then until 1900, most years saw one or no degrees awarded to women. Some women completed all the requisite coursework, but were denied degrees because of their gender. It wasn’t until 1972 that women received even 1 percent of total undergraduate degrees in engineering.
Now: Today, female students are a growing presence in engineering colleges. Of all engineering degrees earned in 2017, 21.3 percent at the bachelor’s level, 25.7 percent at the master’s level and 23.5 percent at the doctoral level went to women, according to data from the American Society of Engineering Education. In total, the percentage of engineering degrees awarded to women was higher in 2017 than it had been since 2008.
The biomedical engineering department has not overlooked undergraduate students, or even younger learners. Sarah Rowlinson, Ph.D., a lecturer and the department’s undergraduate coordinator, leads the charge with these populations by organizing a variety of opportunities for females and underrepresented minorities (including opportunities for grade-school students) to engage with and progress further in engineering education and professional development. For kids, she hosts interactive laboratory activities that provide first-hand experience with the science of engineering. So far, hundreds have participated. Rowlinson also advises several student organizations, in which she encourages female and underrepresented minority students to take leadership positions. Having these students in leadership roles, she says, provides them a greater sense of belonging and “creates a new cycle of underrepresented groups in role model positions to inspire younger students, further aiding in recruiting these populations.” It also opens the door for the students in leadership roles to have more and better opportunities in the future. Such opportunities may include internships, for which Rowlinson seeks to prepare students by leading workshops.
The Importance of Allies The department is making great strides. And, importantly, its progress in attracting and keeping women faculty members and students is not due solely to the efforts of women. Cultural change takes root most firmly when everyone invests.
The proportion of women graduates varies greatly by discipline. In 2017, half of all bachelor’s degrees in environmental engineering went to women. Biomedical engineering was second, with 44 percent of bachelor’s degrees going to women. Still, there are more women in professions such as accounting, medicine and law than in engineering, according to SWE. 10 • FALL 2019
In testament to this, Williams recalled two white, male mentors instrumental in her own education, and their advocacy for her in less-than-comfortable environments. She also praised the department’s male faculty members for their support, saying it overshadows what she’s seen elsewhere.
“The culture is outstanding here,” Williams said. “Our male faculty are our allies. They sympathize. They understand. No questions asked about things, and they’re allies for our students as well — just as much as we are.”

Middle School Summer Camp Empowers the Pursuit of Neuroscience
T
his summer, University of Florida researchers Daniel Ferris, Ph.D., and Rachael Seidler, Ph.D., teamed up to bring more than 20 middle school students to campus for a free, week-long summer camp aimed at empowering girls to explore neuroscience. Held in July, the camp brought sixth, seventh and eighth graders together for hands-on activities, field trips to multiple neuroscience labs and to hear from leading women researchers at UF. Kristine Snyder, Helen Huang, and Julia Kline, three member of Ferris’ laboratory, started the camp at the University of Michigan in 2013 with the goal of providing girls the chance to see themselves at a university and hear from potential role models. The camp has since expanded to additional universities. This was the first time the camp was hosted at UF. Funding for the camp came from a grant to Ferris and Seidler from the National Science Foundation (NSF). Amanda Studnicki and Theresa Hauge, two UF doctoral students led the camp this summer.

We wanted to break the model of what TV and movies show as your typical scientist – boring and old,” Seidler said. “The camp allows girls to see scientists in another way.
“We wanted to break the model of what TV and movies show as your typical scientist – boring and old,” said Seidler, professor in the Department of Applied Physiology and Kinesiology. “The camp allows girls to see scientists in another way.” The curriculum ranged from the basics of muscle and brain physiology, learning about action potentials from the leg of a cockroach, and talking about historical women who made significant scientific and technological advances. Jennifer Nichols, Ph.D., assistant professor, J. Crayton Pruitt Family Department of Biomedical Engineering, led biomechanics activities with the girls using a model of yarn, paper, and straws to mimic how tendons function in the in hand. Aysegul Gunduz, Ph.D., associate professor, J. Crayton Pruitt Family Department of Biomedical Engineering, spoke with the girls about her experience as a woman in STEM and advice she would give her past middleschool self – she talked about the importance of trying new things, regardless of the chance of failure.
While girls are taught to be “perfect,” and boys are taught to be “brave,” it is important for more girls to be brave, Gunduz said. The program also gives campers the chance to get to know the campus, travel from one lab to another and experience college. On the last day, there was an activity called “If I were a neuroscientist” where the girls wrote down what kind of real-world problems they hope to solve in the future. Theresa Hauge, doctoral student in the Department of Applied Physiology and Kinesiology, who helped coorganize the event said, “It was so rewarding watching these girls start the week asking questions about basic brain anatomy and ending it asking questions about their own research ideas in neuroscience. There were campers interested in neuropathologies, prostheses, and neuroimaging to create real-world solutions to the problems around them.”

Machine intelligence for hacking into safer, more accessible care By Laura E. Mize
I
f Ruogu Fang has her way, computed tomography scans of the future will emit about one tenth the radiation of today’s scans, and retinal imaging will one day upend current diagnostic methods for Alzheimer’s and Parkinson’s diseases. An assistant professor in UF’s J. Crayton Pruitt Family Department of Biomedical Engineering, Fang, Ph.D., has been at UF for two years. Previously, she was an assistant professor at Florida International University, where she contributed to efforts to better distinguish and classify the tens of thousands of different types of neurons in the brain. But FIU’s lack of a medical school made it tough to work hand-inhand with physicians and patients to address practical challenges in patient care.
14 • FALL 2019
With UF’s Herbert Wertheim College of Engineering adjacent to UF Health, Fang has teamed up with neuroradiologists and medical physicists from UF Health and from Weill Cornell Medical College and Northwell Health Systems - and is now focused on one of modern medicine’s most commonplace, and seemingly unavoidable, risks of treatment. “Fifty-two percent of the radiation people receive today is from CT imaging, because of the increasing number of CT scans,” Fang explained. For stroke patients, who undergo numerous CT scans to evaluate both damage and recovery, the risks accumulate quickly. But anyone can face increased cancer risk and possibly also the risk of cataract development from repeated CT scans.
Two of Fang’s collaborators are Keith Peters, M.D., an associate professor in the UF College of Medicine’s department of radiology, and Chris Fox, M.D., an associate professor in the college’s department of neurosurgery. Together, they’re using computer programming to glean high-quality data (normally requiring high doses of radiation) from scans created with lowdose radiation. To accomplish their goal, the scientists have “hacked” high-quality scans and studied their underlying computer coding. Based on that, they have created a so-called “training code,” which matches data points picked up during a new scan to corresponding ones found in high-dose scans.
of Parkinson’s disease that are detectable before changes in the brain are. Additional data that may be considered in a new diagnostic process could include visual acuity and other vision information, demographic information, and drug and medical history. Fang believes such a process could be much more accessible than current diagnostic scans, which cost $2,000-$3,000 each and require a trip to an imaging center — an inconvenience patients in cognitive decline may resist.
“We can just apply this network to the low-dose images,” Fang noted, “and the network will naturally output” highquality images with reduced noise and artifacts, as well as superior spatial and temporal resolution. The resulting images match the clarity and quality of a high-dose scan, but with much less radiation exposure. For single-mode CT scans, the team has slashed exposure by 90 percent — for each scan performed. Now, their focus is on doing the same for multimodal CT scans. This portion of the work is funded through a joint grant from the UF Informatics Institute and Clinical and Translational Science Institute. Fang also works with UF Health’s Center for Movement Disorders & Neurorestoration in search of more accessible ways to diagnose Parkinson’s Disease, and to differentiate between subtypes.
Fang, Ramirez-Zamora and Nikolaus McFarland, M.D., Ph.D. (also from UF’s Centers for Movement Disorders & Neurorestoration), use portable scanners — the most accurate being the size of a book. This opens the possibility for scans to be done in physicians’ offices, including nonneurology offices, and other sites. If such a method has merit, the team intends to expand their work to diagnosis of other neurodegenerative disorders.
Fang Focuses on Scientific Approaches to Bridge Data and Medicine • Research Interests:
Her robust research experience related to completely different health conditions — such as her work on early screening methods for diabetic retinopathy — makes her an especially strong collaborator, said Adolfo Ramirez-Zamora, M.D., a UF College of Medicine associate professor of neurology and the center’s director of clinical trials. “This is a great example of how interdisciplinary collaboration can really expand and improve research,” he commented. “We had this hypothesis about maybe looking into patient’s brains through their retinas, but didn’t really have ways for us to do it.”

Fang knew how to approach the project. She and student assistants perform double retinal scans on consenting patients. Using artificial intelligence to analyze the scans, the team is hoping machine learning will uncover “hidden biomarkers” that could be combined with other data “to predict whether the patient has Parkinson’s or not.” This goal is based on recently published studies hinting that vascular, structural, and functional changes in the retina — including thinning of the retinal nerve fiber layer — may be indicators CROSSLINK

hile the statistics are rising and many more women and underrepresented minorities are receiving degrees in engineering, it is no secret that prejudice still exists and the road for success is paved with obstacles. The J. Crayton Pruitt Family Department of Biomedical Engineering (BME) is dedicated to helping students, staff and faculty navigate these obstacles. In this pursuit, Dr. Aysegul Gunduz, associate professor and J. Crayton Pruitt Family Term Fellow, was appointed as the diversity and inclusion officer for the department in Fall 2018. As an international student herself, she is a fierce advocate for diversity issues. She credits her success in research to graduating from highly diverse and inclusive labs. “Diversity and inclusion is our greatest asset - we are at our strongest when we support each other. Our goal is to create a safe and welcoming environment where everyone can thrive,” Gunduz said. During the same semester as her appointment, Gunduz, and recent BME Ph.D. graduate, Olivia Lanier,

met with Herbert Wertheim College of Engineering leadership to discuss concerns regarding sexism, harassment, and discrimination. Since this meeting, the college has implemented numerous policies to increase awareness of resources for women and minorities. The administration also created a diversity and inclusion board for the college, with representatives from every department. Supporting this momentum, Gunduz, Lanier and undergraduate student, Camryn Lewis created a Diversity and Inclusion Initiative within the BME department. The goal of the initiative is to promote equity and social justice and to enhance the education experience by exposing students and faculty to these concepts and challenging them to bring more inclusive actions to the community. At monthly student body meetings, the organization participates in

“Our focus is to continue to create events and programs that focus on cultural competency and student success stories,” Gunduz said. “By celebrating differences and similarities, we hope our BME community will gain a deeper appreciation for one another. diversity training activities, which help promote healthy relationships among people and increase understanding of others’ backgrounds and multicultural perspectives. In addition to these meetings, the organization has hosted numerous events to celebrate diversity.
For Women’s History Month, the organization also hosted an interactive panel discussion with BME professors on a variety of topics challenging women today. The group also attended the annual Equality Florida Gainesville Gala to support LGBTQ+ rights.
For Black History Month, the organization hosted a Black History Celebration that included a special talk from Dr. Curtis Taylor, associate professor and associate dean for undergraduate student affairs at the Herbert Wertheim College of Engineering, commemorating numerous black scientists/engineers. Taylor celebrated the work of black historical figures to an overflowing audience of engaged faculty and students. His presentation was followed by a black history trivia event.
For her efforts with this organization, Gunduz received the 2019 Graduate Education Diversity Champion Award, a joint honor bestowed by the UF Multicultural Association of Graduate Students and the UF Graduate School’s Office of Graduate Diversity Initiatives.
The Diversity and Inclusion Initiative also organized a book drive for local schools. The organization collected over 150 books about black characters and/or written by black authors and donated them to local schools. “Storylines with main black female and male characters are important for children to read, these stories are often misrepresented or excluded from classroom curriculum,” Gunduz said.
Looking forward to next year, the organization aims to recruit more members and expand the number of events that enhance diversity and inclusion. Their mission is for all people who work and study at UF BME to know that their contributions matter and that they will be supported in achieving their full potential. “Our focus is to continue to create events and programs that focus on cultural competency and student success stories, Gunduz said. “By celebrating differences and similarities, we hope our BME community will gain a deeper appreciation for one another.”

Artificial Intelligence adds detail to health assessments in hospital intensive care units
E
very year, more than 5.7 million adults are admitted to intensive care units (ICU) in the United States, costing the health care system more than $67 billion per year. A wealth of information is recorded on each patient in the ICU. Their electronic health records include high-resolution physiological signals, various laboratory tests, and a detailed medical history. Today, nurses build an index of a patient’s status in terms of function and reaction to environmental factors

in the ICU by periodically observing the patient and asking a battery of questions. The process is timeconsuming and often incomplete due to the patient’s condition. Two researchers at the University of Florida are looking toward tomorrow, where indices may be constructed from real-time autonomous observations and analyses of data based on artificial intelligence (AI). Parisa Rashidi, Ph.D., an assistant professor in the J. Crayton Pruitt Family
Department of Biomedical Engineering at the Herbert Wertheim College of Engineering, and Dr. Azra Bihorac, M.D., the R. Glenn Davis professor of medicine in the UF College of Medicine, are collaborating to improve the assessment process for hospital staff and patients. They recently completed a pilot study, in which they examined the feasibility of using pervasive sensing technology and AI for autonomous and highly detailed monitoring in the Intensive Care Unit (ICU).
Rashidi, Bihorac and their research team performed the study on delirious patients and controls in a hospital critical care unit. They employed wearable sensors, light and sound sensors, and a camera to collect data on patients and their environment. Their results showed that granular and autonomous monitoring of critically ill patients and their environment is feasible using a noninvasive system, and they demonstrated its potential for observing and describing critical care patients’ status and their surrounding environmental factors that contribute to sleep disruption and ICU delirium, such as loud background noise, intense room light, and excessive rest-time visits. During the study, the researchers collected the data and subsequently analyzed it using algorithms developed by Rashidi and her engineering students. “AI technology could assist not only in administering repetitive patient assessments in real-time, but also in integrating and interpreting these data sources with electronic health record (EHR) data, thus potentially enabling more timely and targeted medical interventions,” Rashidi said. “We were (also) able to determine that facial expressions, functional status involving extremity movement and postures, and environmental factors, including visitation frequency, light and sound pressure levels at night, were significantly different between the delirious and non-delirious patients,” Bihorac added. The results of this research project were recently published in Nature’s “Scientific Reports.” The paper characterizes the seven different sensing and monitoring mechanisms that were used in the research, which resulted in the most wideranging study of autonomous critical care monitoring to date.
The opportunity for our engineering faculty to collaborate in multidisciplinary studies such as this one enables us to develop and test innovative solutions much more quickly and comprehensively,
The co-location of medicine and engineering colleges on a single campus at the University of Florida has continued to provide an enhanced setting for researchers to perform interdisciplinary studies at an accelerated rate. “The opportunity for our engineering faculty to collaborate in multidisciplinary studies such as this one enables us to develop and test innovative solutions much more quickly and comprehensively,” said Dr. Forrest Masters, Associate Dean for Research and Facilities at the Herbert Wertheim College of Engineering. “The deep relationship our biomedical engineering program has established with our College of Medicine is evidenced by the remarkable work that was done in this study.” For future work, the researchers and their team hope to incorporate real-time analysis of the data from the sensors and be able to provide immediate feedback directly to physicians and nurses as indicators of patient status and even point to possible treatment outcomes.

UF BME Alumnus, Dr. Philip Barish, named in UF’s 40 under 40 M.S., Biomedical Engineering, 2008 Ph.D., Biomedical Engineering, 2011
T
he annual Outstanding Young Alumni awards program was established in 2006 to recognize alumni under the age of 40 whose achievements positively reflect The Gator Nation. 40 Under 40 will continue the tradition of honoring Gators who are reflecting leadership and innovation in their communities and professions. Criteria for the competitive award include making a significant impact on the candidate’s industry and having civic or professional accomplishments at the state, national or international level. Philip Barish, Senior Vice President of Operations and R&D for AbSci has over 17 years of experience in bioengineering research, with expertise in bioprocessing, molecular and cellular biology, biochemistry, protein expression and gene therapy. At AbSci, Barish is responsible for managing research and development activities as well as overseeing business development and strategic partnerships. His own days as a UF engineering student were filled with exciting opportunities. Barish recounts, “During the first year of graduate school, I worked on a group project utilizing an EEG that allowed people to control a video game with their minds. Through combining an EEG and basic signal processing algorithms, our team created a
program that allowed us to navigate a beginner level of a first person shooter game. It was a fascinating engineering project that combined elements of neuroscience and software development to provide a window into brain-machine interfacing.” Things he learned at UF helped Barish take the lead in innovating for success. He said, “AbSci collaborates with leading pharmaceutical companies to enable step-changes in productivity to their bio-pharmaceutical R&D and manufacturing. One of the exciting things about working in startups is that you’re often called onto projects where you lack specific expertise. As our company grew, we had a need to develop a fermentation process for protein production, but we had no one with those credentials in-house. Optimizing fermentation is primarily an exercise in process development, precisely the things you are taught as an engineer, so I volunteered to take on the task. I was able to build out and lead an entire team dedicated to fermentation, which ultimately led me to my current position.”
