I am broadly interested in
Emotional disturbances across development (e.g., affective phenomenology, social determinants, and suicidal/aggressive outcomes)
Statistical methods and software development (e.g., intensive longitudinal data models, machine learning algorithms)
Intersectional minority health disparities via novel modeling approaches (e.g., data mining)
