The goal of my research is to elucidate the molecular basis of behavior. My lab studies the molecular mechanisms of addiction and the role of nicotinic acetylcholine receptors in affective disorders. We use genetic, molecular, pharmacological and behavioral tools in mouse models of drug addiction and depression.
We focus on the nicotinic acetylcholine receptors (nAChRs), which are widely expressed ligand-gated ion channels that modulate neurotransmission. nAChRs are found on many different types of neurons in the brain and are implicated in addiction, anxiety and depression. Our goal is to identify how regulation of nAChRs affects receptor function and behavior. Our main research focus is co-morbid alcohol and nicotine addiction. Alcohol and nicotine are two commonly used drugs, and addiction to both drugs is very prevalent. Alcohol and nicotine addiction have overlapping molecular mechanisms, and identifying these mechanisms will enable us to understand why these drugs are co-abused and to identify new molecular targets for treatment.
