Professional Summary:
With over 400 genes coding for them in humans, ion channels play a significant role in most physiological functions. Drug-induced channel dysfunction often leads to a variety of disorders and results in significant incidence of serious injury and death. We investigate molecular mechanisms underlying neurodegenerative disorders and cardiac arrhythmias induced by ion channel dysfunction arising from genetic factors and/or drug interactions. The tools used for these investigations include genetic, electrophysiologic, pharmacologic, molecular and cell culturing methods. Preparations used for experiments include Drosophila as a genetic model system, and human cell lines expressing human ion channels that play an important role in critical-to-life functions including cardiac rhythm, respiration and the central nervous system.
