Research Interests

I am interested in developing a better understanding of the central mechanisms that govern social behavior using circuit-level and molecular techniques. The neuropeptides oxytocin and vasopressin are centrally-acting mediators of communal interactions, but also influence physiological responses to commonly experienced events such as environmental and internal stressors. Pathological states involving social deficits are often accompanied by dysregulated stress responsiveness and anxiety, suggesting that targeting the oxytocin and/or vasopressin systems may lead to viable therapeutics for psychiatric disorders with pronounced social components. Furthermore, as the prevalence of these disorders can be sexually dimorphic, my interests lie in determining sex-specific mechanisms related to oxytocin and vasopressin expression in the brain.
