I study the dynamics of human pathophysiologic processes by developing mathematical descriptions of complex human disease phenotypes and how they change over time. Pathophysiology may be described at the molecular, cellular, tissue, and organismal levels and may show clinically significant variation over time scales ranging from less than a second to more than a decade. The research combines medical insight, dynamic systems theory, and experiments utilizing microfluidics, video processing, flow cytometry, simulation, and large-scale analysis of medical databases in pursuit of two goals: (1) advancing fundamental understanding of the dynamics of human pathophysiology, and (2) improving patient diagnosis, monitoring, and treatment.
