Genetic Mechanisms of Atrial Fibrillation


About Research Group

As a group we have diverse interests in understanding cellular mechanisms of disease. We have modeled action potentials in neurons, potassium channels in pancreatic beta cells, excitation contraction coupling in cardiomyocytes, and epithelial barrier function in the gut. The common theme is to define mechanisms of ion transport, to understand how transport is altered in disease, and to search for novel therapeutic approaches.
