Dr. Cummings examines the interconnections between affect, related biobehavioral processes (including nonvolitional and volitional self-regulatory systems), and health in the daily lives of youths and young adults with or at-risk for chronic and complex medical conditions (e.g., type 1 diabetes, overweight/obesity, substance use). Within her work, she emphasizes the impact of sociocultural functioning on health and development; thus, she often explores the relationships between key study variables at the individual level as well as within dyads (e.g., parent-child dyads) and examine the translation of findings across diverse populations.
