Research

My research explores the physiological and neurobiological effects of obesity.  Current projects in my laboratory involve diet-induced cognitive impairments, the gut-brain connection (microbiome), and time-restricted feeding paradigms.  I am also interested in the effects of sex differences in physiology and behavior.
