Affiliation: Professor of Medicine, Physiology, Biomedical Engineering and Physics at Washington University in St. Louis. Founder and Director of the Cardiovascular Biophysics Laboratory at WU School of Medicine. He and his students have made seminal contributions to the discovery of new cardiovascular physiology and its mathematical modeling based analysis with rigorous, multi-modal imaging based in-vivo validation. These include: modeling the left ventricle as a suction pump (via the PDF formalism), four-chambered heart as a constant-volume pump, load independent index of diastolic function, left ventricular longitudinal and transverse impedance, intraventricular fluid mechanics and showing that the in-vivo equilibrium volume of the LV is its volume at diastasis, thereby defining passive stiffness as the slope of the diastatic pressure-volume relation. Electromechanical feedback on diastolic chamber properties due to atrial fibrillation.
Affiliation: Graduate Research Assistant in physics at Washington University in St. Louis, in the Department of Internal Medicines Cardiovascular Division, Cardiovascular Biophysics Laboratory. Current focus includes elucidation and characterization of left ventricular chamber properties using multimodal imaging, including echocardiographic image analysis and mathematical modeling of the physiology of diastole. Specific expertise in theoretical physiology, echocardiographic image and hemodynamic signal acquisition and analysis. Research interests: Theoretical and applied cardiovascular physiology
