Personal Statement
My research interest is focused on epigenetic regulation of gene expression patterns in the brain and their effects on social behaviors and psychiatric diseases. Specifically, I have been studying genomic imprinting effects in monoamine neurotransmitter systems of the brain, and their functional impacts on mammalian social behaviors. Genomic imprinting is an epigenetic phenomenon where some genes preferentially express the allele inherited from either the mother (maternally expressed genes) or the father (paternally expressed genes). Imprinting in the brain is hypothesized to regulate social behavior in offspring, and we aim to identify imprinting effects in the brain in order to identify neural circuits that regulate specific aspects of social behavior. My goal as a principle investigator is to make important discoveries in neuroscience while fostering an environment where trainees at all educational and career stages may achieve their full potential.
