Research Interests: My research program is aimed at the understanding of the pathogenesis of cardiac arrhythmias. Our approach involves three main lines of investigation: 1) Elucidation of transcriptional program(s) that regulate the expression of membrane polypeptides involved in determining the duration of cardiac action potential; 2) Investigation of the trafficking and localization of voltage-gated potassium channels in the heart; and 3) Creation of genetically modified animal models for studying sudden cardiac death.
