ACADEMIC BACKGROUND PhD, Biomedical Engineering, Duke University, 1988 MS, Biomedical Engineering, Duke University, 1985 BS, Biomedical Engineering, Duke University, 1983 TEACHING BME 461 - Bioelectric Phenomena BME 423 - Living Systems Analysis RESEARCH My research interests have focused on computational modeling and cardiac mapping strategies to improve understanding of arrhythmia development. Over the course of the past 5 years, those interests have shifted from analyses of electrical interactions between the specialized conduction system and the overlying ventricular myocardium to analyses of electrical source-load interactions that promote conduction failure at the cellular level. In making this shift, I have worked with a number of different investigators to design and test microelectrical mechanical systems (MEMS) arrays containing very small and closely spaced electrodes positioned in the interstitium. The use of MEMS arrays has the potential to provide fundamentally new descriptions of arrhythmia substrate development in heart and tissue preparations at a resolution more commonly associated with single cell electrophysiologic studies. Integration of detailed modeling is advantageous in this regard, as it provides a formal way in which recordings made with the MEMS systems can be interpreted. Microimpedance measurements are a specific focus.
