From 2023 - 2024, Tyler was a Public Voices Fellow with TheOpEdProject in partnership with the AcademyHealth, publishing numerous opinion pieces on health equity in top media outlets, including The Hill and Newsweek. As a MD/PhD candidate, Tyler plans to pursue a PhD in Public Health. Tyler's research focuses on examining structural determinants of health and understanding how to improve the health of marginalized populations. Tyler's research has been published in leading medical and public health journals, such as JAMA Network Open, LGBT Health, and Social Science and Medicine and has been used alongside work with local and international agencies, including the NYC Mayor's Office of Criminal Justice and World Health Organization.

Graduate student

Luis Miguel Mestre, Ph.D., MS, is a Post Doctoral Fellow at The Consultation Center, Department of Psychiatry. Dr. Mestre's got his Ph.D. in Epidemiology with a minor in Data Science from Indiana University School of Public Health-Bloomington; his doctoral training was focused on quantitative epidemiology, statistics, obesity, aging, cigarette smoking, and health disparities. Dr. Mestre's current work as a post-doctoral fellow is in substance use, especially cigarette smoking, health disparities and substance use, and substance and obesity from a psychosocial perspective. Recent projects include polysubstance use in marginalized groups, clinical trials intervention in smoking cessation, food aversion, and eating disorders and their interaction with tobacco use, and substance use and obesity.

I am a Yale medical student who is currently pursuing a research year with the Vascular Medical OutcomeS (VAMOS) lab, where I investigate how social determinants of health impact carotid revascularization outcomes. In addition, I currently sit on the Yale Safety and Security Committee as a Student Representative. My current career goal is becoming an academic medicine cardiologist who conducts clinical outcomes research while providing mentorship to underserved/underrepresented medical students. My premedical, public health, and clinical endeavors have largely been shaped by working with Hispanic/Latino and uninsured/low-income populations. I have also worked with Hispanic/Latino populations through premedical mentorship, serving as the premed liaison for YSM’s Latino Medical Student Association / National Medical Student Association as well as leading the MD cohort for the inaugural Yale PATHS program, where Yale MD / PhD / MD-PhD students provide longitudinal, individualized mentorship for underserved/underrepresented premedical students across the country. I also serve as a medical school Personal Statement Reviewer at the Yale Office of Career Strategy, and advise premedical students in my own time. As Student Representative on the Yale Safety and Security Committee, I help the committee identify and manage safety/security projects such as traffic safety. Prior, I served as YSM Traffic Safety Representative, where I brought classmate concerns to respective committees, advocated and wrote letters/letter templates for local hearings concerning traffic safety, and educated/updated peers on local traffic safety issues. Traffic safety/design is often treated as an afterthought in both the medical and public health realms, when in reality it is a key player for many of the medical/public health disparities we face. Through my endeavors, I hope to make New Haven a safer, more walkable/accessible city.

Alex is a graduate student in the Levy Decision Neuroscience Lab at Yale. She received her B.S. in Neuroscience from the University of Minnesota, Twin Cities where she worked with Drs. Ann Haynos and Lisa Anderson to investigate decision-making and ruminative processes in eating disorders. This work, in tandem with her time in Dr. Ben Hayden's lab examining the neural basis of decision-making in rhesus monkeys, lent to her current interests in translational neuroscience research examining transdiagnostic properties of cognition and behavior. Now as a graduate student in Ifat Levy's lab, she plans to conduct her thesis research on the neural underpinnings of value updating for personally salient foods in obesity with binge eating. Outside of the lab, Alex is passionate about advocating for community well-being and support at the program, university, and national levels.
