My research interests are centered upon how neuropeptide systems and steroid hormones interact within the brain to influence complex behavior. More specifically, a portion of my work focuses on how small physiological changes in serum progesterone levels, which can be increased by a number of environmental and social stimuli, can act upon cells within restricted brain regions to control anxiety-related and social behavior using male rats as a model. One neuropeptide system of particular interest is the vasopressin system, as this system is sexually dimorphic and highly responsive to steroids. The extrahypothalamic vasopressin cells are nearly 100 percent co-expressed with progesterone receptors, and progesterone treatment of male rats suppresses the expression of extrahypothalamic vasopressin in the brain.  Based on these data, I am interested in trying to understand how progesterone influences various vasopressin-linked behaviors, such as social and anxiety-related behaviors, within the male rat brain. The techniques we use to examine these research questions range from protein analysis, gene expression assays, to behavioral analysis. The multi-tiered technical approach used in our lab to examine both behavior and physiology allows us to make meaningful hypothesis about behavioral outcomes.
