My research is concerned with the brain mechanisms underlying learning, memory, and attention. Current studies utilize modern behavioral, chemogenetic, neuroanatomical, and biochemical techniques in rodent models to examine the role of cortical structures and subcortical neurochemical systems in these processes. The ultimate goal of this research is to further our understanding of basic mechanisms of information processing in the brain and ultimately relate these findings to the biological basis of cognitive dysfunction in humans.
