My research is primarily focused on adolescence as a critical period and how socioeconomic disadvantage during adolescence can shape adult mental health through common life transitions, social support, and health behaviors. Relatedly, I am also very interested in early intervention efforts and how to improve preventive measures. In addition to my PhD research, I also conduct studies on learning and pedagogical issues in elementary and high schools.

My position is affiliated with the longtrends project, which investigates how adolescent social inequality impacts disparities in mental health throughout the life course.
