I am interested in behavioral pharmacology and behavioral neuroscience. My research has focused on the role of brain dopamine and GABA systems in behavior. I am currently working on two lines of research. One line of research is focused on understanding the role of dopamine receptors in mediating reinforcing effects of stimuli and the second line of research is focused on identification of drugs that may improve memory via their actions at GABA receptors.
