Research Interests:

My lab is interested in understanding the neural circuits that encode affective (e.g. reward, aversion) information and convert that information into decisions to approach and consume or avoid and reject. We are particularly interested in the role of the neurotransmitter dopamine and neurons of the nucleus accumbens in these processes. Our goals are to understand normal, motivated behavior as well as disorders of motivation including obesity and drug addiction.
