Dr. Bobby Cheon

Principal Investigator


I am currently a Principal Investigator at the Singapore Institute for Clinical Sciences (SICS) and Assistant Professor in the Department of Psychology at Nanyang Technological University. I completed my Ph.D. in Psychology at Northwestern University and completed a postdoctoral fellowship at the Culture Science Institute of Nanyang Business School.

As a social/cultural psychologist, my research focuses on how cultural and environmental influences interact with neurobiological mechanisms to shape social cognition and behavior. I have examined this interplay on processes such as social sensitivity, cooperation, social cohesion, decision-making, and social preferences/prejudices. I adopt a multidisciplinary approach to these research questions, drawing upon methodologies and tools from diverse areas such as experimental psychology, functional neuroimaging, behavioral genetics, and behavioral economics. At the CNRC, I am applying my research experience in the study of culture and social behavior to examine how cultural and social factors modulate food choice, eating behaviors, nutrition and health.
