Research Interest Summary

Sleep and circadian rhythms in regulating affect and motivation

Research Interests

My research focuses on the role of sleep and circadian rhythms in regulating affect and motivation, particularly as relevant to affective disorders and substance use. My current studies focus on adolescents and young adults, employing a combination of experimental and observational methods—including ecological momentary assessment, behavioral tasks, neuroimaging, and objective sleep and circadian rhythm assessments—to investigate mechanisms both in the laboratory and the real world.
