BIOL 131: Human Anatomy & Physiology

BIOL 464: Endocrinology


My research is geared towards understanding endocrine-immune interactions of vertebrates, with a particular interest in how such interactions are shaped by seasonality. Most of my research focuses upon seasonally breeding birds, but rodents are studied as well.  I am also intrigued by sleep and circadian rhythms, and am currently investigating how sleep-wake cycles are regulated in animals inhabiting polar environments, most notably the Arctic. Nearly all of the research in my lab has biomedical applications and more specifically is related to several health-related fields, including endocrinology, stress physiology, epidemiology, immunology, and neuroscience.
