I examine biobehavioral and psychosocial models of eating disorders and obesity with a focus on momentary processes that predict behaviors.


Tyler Mason, Ph.D., is an Assistant Clinical Professor in the Department of Population and Public Health Sciences at the University of Southern California and Associate Director of the Real-Time Eating Activity and Children’s Health (REACH) lab. Broadly, his research interests include the etiology and treatment of eating disorders and obesity. In particular, his research studies trait- and state-based processes that affect individuals’ ability to engage in self-regulation and goal-directed behaviors among diverse groups such as adults, children, and minorities. Specifically, he investigates how the interplay of factors such as affect, executive functioning, and social stressors are associated with unhealthy behaviors in the context of regulatory, control, and goal theories. Much of this research uses ecological momentary assessment to measure the momentary processes that maintain various eating and diet behaviors and physical activity. Further, he is interested in the use of advanced statistical methodology to further obesity and eating disorder research including multilevel modeling, latent variable modeling, and network analysis. His research has culminated in over 143 peer-reviewed journal articles and book chapters, and his research has been featured in top journals such as Psychological Bulletin, Health Psychology, Obesity, and the International Journal of Eating Disorders. Finally, he serves on the editorial boards of two international peer-reviewed journals: Eating Behaviors and Eating and Weight Disorders.
