Dr. Brant Hasler is the principal investigator of the Social Jet Lag in Teens and the SLATE research studies. His research focuses on the role of sleep and circadian rhythm 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 director of our accredited Behavioral Sleep Medicine training fellowship. In his free time, Dr. Hasler enjoys trying new restaurants, cooking at home, hiking, biking, and hanging out with his daughter and her trusty canine sidekick, Stellaluna. Dr. Hasler is much better able to enjoy his free time ever since he assembled such a hard-working, responsible, intelligent, and fun team (see below).
