Gregg is a PhD student in the Psychology department at Stanford University. Collaborating with public and private organizations, he uses national surveys and field studies to develop and assess social psychological interventions to encourage conservation behaviors including reducing meat consumption, conserving household water and reducing home energy use. In these domains, he examines the role of key psychological drivers of action such as social norms, identities, and morality. His research aims to better understand collective action and address critical psychological barriers in living more sustainably.
Gregg received his undergraduate degree in psychology and anthropology from the University of California, Berkeley. There, he completed a honors thesis on prosociality and cooperation. After graduating, he served as a lab manager for the Institute of Personality and Social Research and the Culture and Cognition Lab. Before coming to Stanford, Gregg worked as a research associate and volunteered for the Greater Good Science Center.
