Sean Bradley received his B.A. in Psychology (Hons) & Philosophy from Bucknell University in 2006 and Ph.D. from the University of Chicago in 2013. His graduate research at University of Chicago’s Institute for Mind and Biology under the supervision of Dr. Brian Prendergast focused on the bidirectional influence of circadian and seasonal rhythms on aspects of peripheral physiology. This work focused on the ability of rhythmic food availability to drive circadian rhythms in hormones, energy balance, and the immune system. He went on to join Dr. Timothy Bartness at Georgia State University’s Center for Obesity Reversal investigating the neural substrates of food-seeking behavior. Outside of the laboratory, Sean spends his time painting and fostering rescue dogs.
