My research focuses on low levels of prenatal ethanol exposure and the subsequent effects on the drinking of the child as it age. More specifically, I am interested in the changes that are occurring in the brain after these low levels (just a few drinks throughout the whole pregnancy) of exposure in the womb that lead to increased risk of alcoholism.
Currently my research has begun to focus on the transgenerational transfer of alcohol preference. Specifically I am interested in epigenetic effects of prenatal alcohol on the fetus and possible transfer across generations. In order to explore this questions I have been awarded an NIH grant for 2 years in the amount of $270,000.
Another aspect of my current research has to do with impulsivity. I am testing whether prenatal ethanol exposure makes the animals more impulsive and that this is the driving force behind increased probability for alcohol abuse.
