Our research is focused on understanding the neurobiological mechanisms of drug addiction, obesity and schizophrenia, with an emphasis on the role of nicotinic acetylcholine receptors (nAChRs) in these processes. We employ a multidisciplinary approach that includes complex behavioral paradigms, physiological analyses and molecular biological techniques. Current projects include the utilization of vector-based delivery systems to modify gene expression in the brains of rodents to identify novel signaling cascades that may play a role in addiction-like behaviors.
