Professional Interests

My research is focused on cardiac arrhythmias (abnormal heart rhythms), particularly in heart failure. We use an integrated approach from proteins to cells to tissues to the intact organism to study the causes, and potential treatments of cardiac arrhythmias. My clinical practice is at the Ambulatory Care Center at the Ross Heart Hospital, where I provide patient care in antiarrhythmic medication monitoring.
