My research focuses on children's emotional development. In particular, I am interested in the ways in which the family system contributes to children's development of (mal)adaptive emotion skills and the role of these emotion skills in child psychopathology. I seek to translate this knowledge to the clinical care context as a means of gaining insight into how treatment approaches might be adapted to maximize therapeutic outcomes for youth.
