Letter from the Chair
Dear EHS Family,
I am honored to introduce the Spring 2026 EHS Newsletter and to share highlights with you.
The department has been operating at full speed this semester, and it has been wonderful to see students, staff, and faculty working together. Our Monday seminars and capstone presentations provide valuable platforms for students and trainees to showcase their outstanding work, offering a firsthand glimpse of how the next generation of public health leaders engage and communicate with the public. The 2026 Granville H. Sewell Distinguished Lecture and the EHS Distinguished Professor Lecture Series also reflect the environment EHS fosters for the exchange of scientific ideas and collaboration. I hope the impact and momentum of this productive year are as inspiring to you as they are to me.
At the same time, the environmental health challenges affecting society call on us to be even more creative, thoughtful, and strategic. Our faculty remain at the forefront of these activities, extending their reach to protect public health. Recent examples include the publication on the dangers of reversing the endangerment finding by Dr. Cecilia Sorensen and colleagues in HealthAffairs, Dr. Robbie M. Parks’ participation in the 2025 United Nations Climate Change Conference (COP30) in Belém, Brazil, and Dr. Ami Zota’s briefing of policymakers on the importance of robust pre-market safety reviews, particularly for children. These accomplishments represent only a small fraction of the many ways our faculty model for students how to integrate research and communication to maximize public health impact.
With graduation approaching, I’m proud to acknowledge the impressive work being done across the department and excited to follow the achievements of our graduates. The summer months will provide opportunities to reflect on our research and educational programs and to support our students engaging in applied practice experiences and summer research programs, such as SHARP. I’m also thrilled that PrIMER (ProgramtoInspireandMentorUndergraduatesinEnvironmentalHealth ScienceResearch) will be back this summer. Let’s enjoy the summer months with great EHS work and spirit!

Grant Tore, MPH '20
Grant published the first chapter of his dissertation, "Associationsbetweenexposuretopolycyclicaromatic hydrocarbonsandbiomarkersofacutekidneyinjury amongChileanagriculturalworkers," in the International Journal of Hygiene and Environmental Health.
The analysis examined exposures to polycyclic aromatic hydrocarbons (PAHs), likely resulting from widespread residential wood burning, and their associations with biomarkers of acute kidney injury among male agricultural workers in Chile. Specifically, they found that select PAH exposure were associated higher urinary concentrations of IL-18, a biomarker of kidney inflammation.

Dr. Carolyn Gigot, Postdoctoral Research Scientist
Dr. Gigot received the American Diabetes Association Postdoctoral Fellowship, starting this February 2026 for up to 3 years! Her project title is Occupationalandenvironmentalmetalsexposuresand diabetesrisk:mixturesandmodifiablefactorsinthe Multi-EthnicStudyofAtherosclerosis(MESA), and her mentor is Dr. Ana Navas-Acien.
Scientific abstract: A growing body of experimental and epidemiological evidence links occupational and environmental metals exposures (e.g., arsenic, cadmium, and zinc) to type 2 diabetes (T2D).
However, the chronic cumulative and interactive effects, which are most relevant for regulatory settings, remain largely unexplored. Further, other job-based exposures (psychosocial stress, shift work) may contribute independently to T2D risk and modify the impact of metals exposures given shared biological Mechanisms.
Hypothesis: Exposure to metals mixtures and occupational stressors independently and jointly increase T2D risk. This work will evaluate prospective associations of urinary metals mixtures (Aim 1) and job characteristics, including job-based metals exposure, work-related stress, and work hours (Aim 2), with T2D, and potential effect modification by demographic, nutrition, or lifestyle characteristics. Also assessed is the potential for stress or work hours to modify the association between urinary metals and T2D (Aim 3).
The proposed project will use existing data from the Multi-Ethnic Study of Atherosclerosis (MESA), a diverse, prospective cohort with over 22 years of follow-up (N ≈ 5700). At baseline, participants provided biospecimens for quantification of 16 urinary metals and completed validated questionnaires on sociodemographic, behavioral, and occupational characteristics. This work will determine associations of occupational and environmental exposures with incident T2D and continuous glycemic measures, followed by machine learning approaches to investigate overall and interactive associations of mixtures. Findings will identify novel modifiable risk factors and susceptible populations, supporting environmental health policy and occupational protections, as well as precision medicine prevention strategies to reduce the burden of T2D.

Dr. Ami Zota
On April 1, Dr. Zota inaugurated the Environmental Health Sciences Distinguished Professor Lecture Series, which recognizes faculty promotion and highlights impactful research.
In her presentation “WhereScienceMeetsJustice: Environmental Healthasa CatalystforSocialChange” Dr. Zota described her journey to becoming a leading researcher in environmental justice and health equity, highlighting how science-based advocacy within environmental health research can advance health-protective legislation, such as the Washington Toxic-Free Cosmetics Act. She emphasized media engagement as a tool for amplifying diverse voices within research and strengthening ties between scientists and the public, an approach that led her to found the Agents of Change in Environmental Justice program.
Dr. Zota concluded the talk by sharing her own strategies for maximizing scientific impact, encouraging attendees to stay open-minded, embrace collaboration, and pursue ambitious goals.
Spotlights: MPH Student
Ana Hernandez Vega, MPH 2nd Year
Ana will begin her PhD in Environmental Health Sciences at UCLA under the mentorship of Dr. Yoshira Ornelas Van Horne. Building on her APEx experience this summer, she hopes to continue researching the health impacts of occupational exposures, including pesticides, while advancing awareness of the need for stronger policies and regulations.
During her time in EHS, Ana’s involvement in research, teaching assistantships, and coursework, including Determinants of Public Health and Occupational Health & Safety, inspired her to pursue this path.
She is deeply grateful to the department and to her mentors, Dr. Maya Deyssenroth, Dr. Greg Freyer, and Nina Kulacki, for their guidance and support!
Spotlights: Doctoral Alumni
Dr. Nina Flores
Dr. Flores, EHS 2025 PhD graduate and current postdoctoral fellow in the Promoting Equity in Cardiovascular and Respiratory Health training program jointly based at the UT Austin School of Social Work and Dell Medical School, earned the American Thoracic Society's Annual Meeting’s Margaret Becklake Award for her abstract titled "System-wideMold InterventionReduced Asthma EDVisitsinNew YorkCityPublicHousingDifferentiallyAcross BuildingandNeighborhoodCharacteristics."
The Becklake Award, named for the pioneering occupational and environmental lung health researcher Dr. Margaret Becklake, is given annually for the best Environmental and Population Health abstract involving work in low- or middle-income countries or addressing international and socioeconomic health disparities. Dr. Flores’s abstract reported on research from her dissertation that examined the impact of NYCHA's "Mold Busters" program, a city-wide mold remediation initiative serving over 400,000 predominantly Black, Hispanic, and low-income public housing residents in New York City, on asthma-related emergency department visits. Using doubly robust differences-in-differences analyses and latent class growth modeling, Dr. Flores and her co-authors found that the intervention was associated with a reduction in asthma-related ED visits that translated to approximately 2,798 fewer ED visits per year and that buildings in higher-poverty neighborhoods and flood zones with older infrastructure experienced slower reductions in mold complaints and correspondingly smaller improvements in asthma outcomes. The work exemplifies the spirit of the Becklake Award by demonstrating that largescale environmental health interventions can serve as powerful tools to address longstanding respiratory health disparities among vulnerable, low-income urban populations. 9
PrIMER Summer 2026!
Grace Cammarata, MPH 2nd Year
This summer, I will serve as a mentor to 2026 PrIMER undergraduate trainees. As pathways programs have been defunded across universities and the PrIMER program could not occur last summer, the significance of this statement cannot be overstated. My journey in Environmental Health Sciences began as a PrIMER trainee during the Summer of 2024 as a rising Senior at New York University. Through PrIMER, I had the opportunity to work alongside and learn from Dr. Herbstman and Maricela Ureño at the Center for Children’s Environmental Health, where I disseminated report-back documents on PAH exposure during pregnancy and connected with Washington Heights community members.
Over the course of the summer, I built a vast network of friendships and mentors. Among these is Dr. Ana Navas-Acien, the first person to assure me that I belong in this field, and someone whom I am continuously grateful to have in my corner. Now, I am on the cusp of completing the first year of my MPH in the EHS department, where I am researching arsenic and uranium exposure in drinking water with Dr. Anne Nigra, and am preparing to begin my Apex with WE ACT for Environmental Justice. These achievements would not have been possible without the personal, academic, and financial support that PrIMER has provided me. I am so excited to meet the incoming trainees and to support the next wave of environmental health changemakers!

Sewell Lecture
Watch the talk HERE!
On March 12, EHS welcomed Dr. Carlos Santos-Burgoa who presented "ReimaginePublicHealthProtection" as part of the 2026 Granville H. Sewell Distinguished Lecture.
During the lecture, Dr. Santos-Burgoa reflected on the early identification of 1,3-butadiene as a human carcinogen and described how industry-funded research and stalled rulemaking have slowed meaningful public health protections. He presented findings from a study of regulatory bodies in 12 countries showing limited capacity to measure health impact and to resist regulatory capture by industrial and political interests.
Dr. Santos-Burgoa stressed that, moving forward, regulatory institutions must be redesigned to function as effective public health protection authorities.
