Research

I am generally interested in how the neuroendocrine system interacts with the reproductive and immune systems early in life, and how those interactions affect physiology and behavior in Siberian hamsters. More specifically, I am interested in studying sex differences in physiology and behavior and determining the mechanisms mediating those sex-specific effects.

Research

My research interests lie in several different fields, including behavioral endocrinology, sensory biology, and neuroethology. As part of my rotation project in the Demas lab, I am examining the effects of photoperiod and melatonin administration on seasonal aggression in male Siberian hamsters (Phodopus sungorus). For this study, I am utilizing molecular, physiological, and behavioral techniques to gain insight into the neuroendocrine basis of aggression in seasonally-breeding mammals.
