Sakari Lemola, PhD (Associate Professor)

Sakari Lemola  


My research interest is on positive development at different stages of the life cycle. In particular, I am interested in the relationship between positive development and (1) early life adversities, (2) sleep patterns, and (3) emotional support in the partner relationship. In a related vein, I am interested in the prevention of (4) early life adversities and (5) consequences of insufficient and poor sleep, particularly during adolescence.
