Faculty Collaborators

DiSH Lab Alumni
Dr. Jeffrey Hunger
Broadly speaking, Jeff is interested in using insights from social and personality psychology to understand and improve population health. Jeff is particularly interested in the mechanisms by which social and structural conditions (e.g., discrimination) can contribute to poorer mental and physical health among stigmatized populations. Much of his current work is focused on elucidating the mental and physical effects of weight-based social identity threat. In other lines of research, Jeff examines factors that contribute to (and mitigate) anti-fat bias, exploring the potentially detrimental consequences of perceiving oneself as “overweight,” and working to understand the personal and social influences on cardiometabolic health among higher bodyweight individuals.

Angela is a 2018 DiSH Lab graduate. She is now an Assistant Professor of Psychology at Worcester Polytechnic Institute in the Department of Social Science and Policy Studies. Her program of research focuses on understanding how various psychological and biological stressors can influence our eating behaviors and weight, and how our eating behaviors and weight can, in turn, lead to psychological and biological stress.

He is now a UX researcher at Square working on products and services that help small businesses sell online. He was initially interested in studying basic laws of learning and memory but soon discovered whacky things kept happening when food was involved in his experiments. He has since joined Dr. Tomiyama’s lab and is now primarily interested in how basic learning and memory processes influence eating behaviors and, conversely, how eating behaviors may be governed by unique learning and memory processes. He received his undergraduate training at Binghamton University and is an avid fan of Chelsea FC. To see more about what Ben is up to, check out his personal page here.
