Postdoc Alumni

Justin Caouette, Ph.D.

Justin earned his PhD in Human Development from the University of California – Davis in 2016. Prior to that, he graduated summa cum laude from Claremont McKenna College in 2008, with honors in Psychology. From 2016 to 2018, he was a postdoctoral researcher at OHSU, as well as a research fellow through the OHSU Oregon Clinical and Translational Research Institute (OCTRI) – Oregon Students Learning and Experiencing Research (OSLER) TL1 program. Justin’s research uses fMRI methods to study peer social influences on adolescent and emerging adult affective health (e.g., anxiety, depression) and behavioral health (e.g., substance use, sexual health). As of 2019, Justin is serving as the inaugural Associate Director of Prevention Science Academic Programs, within the College of Education at the University of Oregon.

Tara Chowdhury, Ph.D.

Tara earned her B.S. at UCLA in Neuroscience with a minor in Mathematics. During her PhD in Chiye Aoki’s lab at NYU, Tara studied a rodent model for anorexia nervosa, discovering that the rodent hippocampus undergoes large-scale dendritic remodeling during adolescence, and the experiences of exercise and food restriction had distinct effects on hippocampal circuitry. Tara went on to a postdoc in Bita Moghaddam’s lab at OHSU to study sex differences in the rodent reward system hoping to understand why men and women are vulnerable to different psychiatric conditions. Tara is primarily interested in understanding vulnerability to psychiatric illness. She joined Dr. Feldstein Ewing’s lab as a postdoctoral researcher from 2019 to 2020 to shift gears toward human subjects research and to explore how the insights and hypotheses from animal research can be used to improve adolescent mental health. Tara’s publications are available here [].
