Biographical Sketch

My laboratory studies ion channel proteins of nerve and muscle. We investigate the basis for inherited diseases of these genes, as channelopathy disorders such as myotonia and periodic paralysis. We also use electrophysiological and computational approaches to study the mechanisms of voltage-gating in ion channels. A new area of research is the study of neurotransmitter receptors with a focus on the role of neuronal, nicotinic acetylcholine receptors as a target of drug therapy in the treatment of Parkinson's disease.
