Curiosity about Social Interaction

“Some tables were really outgoing, super playful and loud, while other tables had students sitting quietly where everyone was reading a book or staring down at their sandwiches to avoid conversation. I always found this interesting that everywhere you go you would find some people who were more outgoing and others who were shier and more introverted. I never really stopped paying attention to that.”
— Benjamin A. Rein, PhD

Rein recalls observing different social dynamics during his elementary school lunch periods, noting the range of social engagement from lively groups to quiet, reserved individuals.

Academic Credentials

Rein completed his doctoral degree in neuroscience at the Jacobs School of Medicine and Biomedical Sciences, where he conducted research in the lab of Zhen Yan, PhD, SUNY Distinguished Professor of physiology and biophysics.
