Research in my laboratory is focused on systems engineering approaches to understanding the operation of physiological systems in health and disease. A recent major effort in our group has been on theoretical and experimental characterization of the thermodynamics, kinetics, and electrophysiology of cardiac mitochondria. We use computational simulation to translate our findings on the function at the organelle level to analyze and interpret in vivo data on cardiac energetics obtained, for example, from 31P-magnetic resonance spectroscopy. Similarly, the development of a mechanistic understanding of the long-term and short-term responses of the myocardium to ischemia and hypoxia requires the development of a model that can predict the effects of modulating expression and activity of mitochondrial and sarcolemmal ion channels on whole-heart mechanical function. This work involves building integrated models of cardiac mechanics, energetics, mitochondrial ion handling, and microvascular oxygen transport. Additional research interests include non-equilibrium thermodynamics in biochemical networks, mass transport and microvascular exchange in physiological systems, and drug metabolism and physiologically-based pharmacokinetics. All of these efforts involve a multi-disciplinary team of mathematicians, engineers, and biologists at the Medical College of Wisconsin.
