Research
I am a behavioral neuroendocrinologist; this means I’m interested in the relationship between the brain, hormones, and behavior. In my lab, we primarily study reproductive behaviors. I am interested in several aspects of reproductive behavior--including attraction, copulation, and pregnancy/postpartum--and my lab group is working to identify neural correlates and sites of neuroplasticity associated with each. Our research takes a comprehensive technical approach, ranging from the cellular/molecular to the systems/behavioral levels of analysis. We use hamsters and mice to model these complex brain-hormone-behavior relationships under simpler and more controlled conditions. Our goal is to understand fundamental principles of neurobiology that can be applied to improve human health.
