Personal Statement:  My research interests are in cardiac electrophysiology, arrhythmias, and sudden death. I have been active in this field for many years and research in my laboratory spans the entire spectrum from the molecular/cellular mechanisms of cardiac arrhythmias to clinical studies in patients using novel imaging techniques developed in my lab. The research on molecular/cellular mechanisms of arrhythmias has been supported by the NIH-NHLBI grant “Cardiac Excitation and Arrhythmias”. Mathematical models of cardiac cells, developed under this grant, have been used for cardiac electrophysiology and arrhythmia simulation studies in many laboratories worldwide. The development of a novel noninvasive imaging modality for cardiac electrophysiology (ECG Imaging, ECGI) and its application in the study of human arrhythmia mechanisms has been supported by the NIH-NHLBI grant “Inverse and Forward Problems in Electrocardiography” – an NIH MERIT award recipient. I have trained many graduate students and post-doctoral fellows (in basic science and clinical departments) to become independent researchers. I am also the director of the Cardiac Bioelectricity and Arrhythmia Center (CBAC) that includes 39 faculty members and fosters interdisciplinary research, from cell to bedside, in the cardiac electrophysiology and arrhythmia field.

Newport Beach, CA, December 2014. Contribution to Science
My contributions to science can be grouped into two major areas of cardiac electrophysiology: 1. Studies of basic mechanisms using mathematical modeling and computer simulations, and 2. Development of a novel noninvasive imaging modality for cardiac electrophysiology (Electrocardiographic Imaging, ECGI) and its application to study mechanisms of cardiac arrhythmias in patients.
My laboratory pioneered the development and application of detailed, physiologically accurate mathematical models of cardiac myocytes. These species-specific models have been used extensively by us and in other laboratories worldwide for research and training. The first published model of the guinea pig ventricular cell (Circulation Research 1991 and 1994) has been included in textbooks in many languages. To date, we have published models of the canine and the human myocytes which simulate the cell electrophysiology and calcium cycling and include regulatory pathways (the CaMKII pathway and beta-adrenergic cascade). We have used modeling to connect genotype to phenotype in hereditary cardiac arrhythmias, thereby providing a new computational-biology approach for relating phenotype to phenotype in other pathologies. Simulations were conducted to study the electrophysiological consequences and underlying mechanisms in various pathologies (e.g. ischemia and infarction, calcium overload). We also established basic principles of intercellular communication and action potential propagation in cardiac tissue, including definitions of important quantitative parameters such as the safety factor for conduction and the vulnerable window for unidirectional block and reentry. In addition, modeling was used to relate the electrocardiogram to underlying ion-channel and cellular properties in the normal myocardium and in various pathologies. Representative publications are listed below:

The only noninvasive method for assessing cardiac electrical function has been the electrocardiogram, which was introduced 112 years ago. While very useful in clinical practice, it is severely limited in resolution, sensitivity and specificity because it records a few signals on the body surface, far away from the heart. To overcome these limitations, we developed a novel imaging modality (similar in concept to CT or MRI) for noninvasive mapping of the electrical activity of the heart and cardiac electrophysiologic substrate. After a long period of validation in animal experiments and in patients undergoing cardiac surgery, we published the first human application in 2004 (Nature Medicine). This new method is called Electrocardiographic Imaging (ECGI); its resolution is about 6mm on the heart surface. The technology has already been translated to clinical application by CardioInsight Technologies. In my lab, we are using ECGI to study in patients the mechanisms of various cardiac arrhythmias the properties of arrhythmic substrates, and the consequences of therapeutic interventions such as catheter ablation of atrial fibrillation and cardiac resynchronization therapy in heart failure.
