Bobby Kyungbeom Cheon, Ph.D.
Stadtman Investigator
Social and Behavioral Sciences Branch
NICHD/DIPHR
Research Topics
Dr. Cheon investigates the influence of social and psychological factors on human appetite, eating behaviors, and diet-related chronic diseases (e.g., obesity). His research also examines how disparities in obesity and cardiometabolic disorders emerge from the influence of socioeconomic adversity on food choices and eating behaviors. Using a combination of experimental studies, observational research, and population-level approaches, he investigates how social influences and socioeconomic vulnerabilities shape food-related behaviors and health outcomes. Through this work, he seeks to (1) identify psychological factors that promote obesogenic eating behaviors, (2) improve prediction of which children are at greater risk (or show resilience) to developing obesity and cardiometabolic disorders later in life, and (3) inform interventions aimed at reducing health disparities in these conditions.
