Dr. Hasler’s research focuses on the role of sleep and circadian rhythms in regulating affect and motivation, particularly as relevant to affective disorders and substance abuse. In addition to his research program, Dr. Hasler is actively engaged in research mentorship and clinical supervision, as well as direct clinical practice, and is the Co-Director of our accredited Behavioral Sleep Medicine training fellowship.
