Research Bio

Research in the Biological Rhythms Laboratory focuses on how mammals orient in time, with emphasis on reproductive physiology and behavior, hibernation, daily torpor, body weight,and adipose tissue regulation in several rodent species. Long-term interests include the role of the suprachiasmatic nucleus of the hypothalamus as a circadian and circannual pacemaker and the function of the pineal hormone melatonin as the endocrine signal through which light influences seasonal rhythms.
