I am a cardiovascular epidemiologist with formal training in cardiology, epidemiology, and health services research. My research focuses on population electrocardiography with particular emphasis on improving the methodology of electrocardiogram (ECG) recording in population studies and the utilization of ECG markers in the assessment and prediction of cardiovascular disease (CVD) risk.

Currently, I am a tenured professor of cardiology and director of the EPICARE ECG Center, the reading center for several NIH-funded studies. This includes ARIC, MESA, CARDIA, HCHS/SOL, ACCORD, SPRINT, LookAHEAD, and many others. Utilizing data from these studies, we managed to develop numerous novel ECG markers highly predictive of cardiovascular diseases, including heart failure, sudden cardiac death, coronary heart disease, stroke, and atrial fibrillation.

In terms of ECG methodology, I've established normative reference ranges for heart rate variability from resting ECG, created a new PR-heart-rate correction formula, developed new techniques for quality control of ECG recording in population studies, and invented a new ECG cable that minimizes switching errors of ECG cables during recording. In conclusion, I have devoted the past two decades to an academic career that combines research, education, administration, and advocacy.
