Research in our lab is focused on understating the mechanisms underlying social behavior deficits in autism spectrum disorder (ASD) and the implication of the hypothalamic oxytocin system in ASD and other neurodevelopmental disorders.
Social behavior is modulated by brain regions, which form brain circuits through functional and anatomical connectivity. Information processing within these neural circuits is not hard-wired but rather adaptive to the surrounding environment, in part due to the activity of neuromodulators such as oxytocin. In our lab, we are interested in understanding how oxytocin neurons in the hypothalamus behave during social behaviors. We are also interested in studying the impact of mutations in high risk genes for ASD on the hypothalamic oxytocin system and the implication of the this system in social behavior deficits, which are a core symptom of ASD.
Current projects in our lab include (1) studying the effect of mutations in the Shank3 gene, a high risk gene for ASD, on social brain circuits involving the oxytocin system, (2) understanding basic mechanisms of function of oxytocin neurons during social behavior, and (3) improving oxytocin and other peptide delivery to the brain.
To address our scientific questions and to dissect molecular pathways and neural circuits of social behavior, we use transgenic rat models for ASD and apply behavioral and molecular neuroscience approaches, including, fiber photometry, brain microdialysis, and cutting-edge chemo-genetic tools.
