Research Assistant Professor

I am currently investigating nicotine-induced sex differences in adult rats. Specifically, I examine if acute and repeated intravenous nicotine or cocaine administration produces sex dependent changes in dopamine transporters and dopamine D1, D2, and D3 receptors in the mesolimbic and nigrostriatal pathways, and how these changes may mediate the expression of nicotine or cocaine–induced sex differences in rats.
