Gregory E. Demas studies how hormones, the brain, the immune system, and the environment interact to shape animal behavior and physiology, often using seasonal animals such as Siberian hamsters as models. His work spans topics like how day-length and melatonin drive seasonal changes in aggression and reproduction, how illness affects social behavior, and how the gut microbiome influences brain and immune function. This research bridges neuroendocrinology (hormone-brain interactions) with ecology and immunology.
