My research focuses on using mathematical methods to model and better understand cardiac muscle cells; delineating Ca2+ mediated signaling, excitation-contraction coupling, excitation-transcription coupling, and energy metabolism. These studies have the common theme of developing mathematical models in terms of ordinary and partial differential equations, numerical methods, and dynamic systems analysis in order to solve problems. In the long-term, these types of systems analyses at the cellular level will be important for developing an organ- and system-level understanding of the heart and cardiovascular system, in health and disease.
