Professional Summary:
My research focuses on how prenatal environmental factors such as prenatal ethanol exposure and prenatal stress exposure alter various brain functions leading to persistent cognitive and behavioral deficits (e.g. impaired executive function, increased addiction risk, and anxiety) later in life. We also study how postnatal environment can ameliorate or further exacerbate these deficits. A new focused area is the contribution of neuroinflammation in ethanol exposure-induced cellular and behavioral effects. A wide array of techniques is used in my research, including cellular/system electrophysiology, immunocytochemistry, and various behavioral techniques coupled with optogenetic and fiber photometry approaches. These techniques allow us to investigate changes in brain functions at cellular, circuitry, and behavioral levels. Our major discovery is that prenatal ethanol or prenatal stress exposure leads to over-excitation of dopamine (DA) neurons located in the ventral tegmental area (VTA) and enhance their responses to drugs of abuse resulting in increased addiction risk. In addition, we are investigating how prenatal ethanol exposure leads to cellular/molecular changes underlying impaired executive function and anxiety-like behaviors. My research contributes to the understanding of brain mechanisms mediating cognitive and behavioral deficits in fetal alcohol spectrum disorders (FASD). These findings may lead to better treatment strategies of FASD
