Postdoctoral Fellows

Current Postdoctoral Scholars

Heather R. Farmer, Ph.D.

Dr. Heather Farmer is a Postdoctoral Fellow at the Center for the Study of Aging and Human Development at Duke University Medical Center. She studied both gerontology and public health at the University of South Florida and completed her Ph.D. in Biobehavioral Health at Penn State University. In her dissertation, Dr. Farmer used data from the Health and Retirement Study to examine how the interaction of race, gender, and SES lead to differences in stress-related biomarkers (e.g., C-reactive protein) and the potential role that acute and chronic exposures to discrimination played in the associations. Dr. Farmer’s mentor is Matthew E. Dupre, Ph.D., Associate Professor in Population Health Sciences. In her research during this postdoctoral fellowship, Dr. Farmer will apply an intersectionality framework to understand how race, gender, and socioeconomic status (SES) interact to produce inequalities in health.

Collin W. Mueller, Ph.D.

Collin W. Mueller, Ph.D. is a Postdoctoral Fellow in the Center for the Study of Aging and Human Development at Duke University. Dr. Mueller specializes in mixed methods research design and team-based ethnographic and qualitative interviewing techniques. His program of research is conceptually grounded in life course perspectives, relational ethnography, and cumulative advantage/disadvantage approaches. His co-mentors are Karen E. Steinhauser, Ph.D. (Professor in Population Health Sciences), Kimberly S. Johnson, M.D. (Associate Professor of Medicine-Geriatrics), and Tyson Brown, Ph.D. (Assistant Professor of Sociology). Dr. Mueller’s current research explores how social status, exposure to stress and the availability of psycho-social coping resources, healthcare usage trajectories, and changes in health status unfold as individuals age, and how understanding these processes can better inform primary health care delivery for disadvantaged patients and contribute to policy interventions to more effectively reduce health disparities among older adults.
