My research is devoted to understanding the neurobiology of social behavior. My focus is on elucidating the role of the neuropeptides, oxytocin and vasopressin in regulating neural pathways of innate social behavior in male and female mice. Specifically, I am interested in understanding how oxytocin and vasopressin modulate neuronal activity in discrete brain regions known to regulate social behaviors, including pheromonal communication, social memory, courtship and mating behaviors, and how this modulation differs between the sexes. Working with Dr. Ian Davison, I am currently using chronically implanted, open source mini endoscopes combined with calcium imaging in the accessory olfactory bulb to observe population-level encoding of different conspecifics during natural social interactions in freely behaving mice. This work is relevant to many neuropsychiatric disorders with core social behavioral alterations, including autism, schizophrenia, and depression.
