Bio: I am a Professor of Mathematics (and The Michael and Eugenia Brin Endowed E-Nnovate Chair in Mathematics) at the Department of Mathematics, University of Maryland, College Park. My research work focuses on using mathematical approaches (modeling, rigorous analysis, and data analytics) to gain insight and provide understanding on the transmission dynamics of emerging and re-emerging infectious diseases of public health significance. Specifically, I design, analyze, parameterize, and simulate novel models for the transmission dynamics and control of emerging and re-emerging infectious diseases. My research also involves the qualitative theory of nonlinear dynamical systems arising in the mathematical modeling of phenomena in population biology (ecology, epidemiology, immunology etc.) and computational mathematics (with emphasis on the design of robust numerical methods that give results that are dynamically-consistent with the governing continuous-time model being discretized). The ultimate objective of my research work, in addition to the development of advanced (and perhaps novel) mathematical theory and methodologies for studying nonlinear dynamical systems arising in population biology, is to contribute to the development of effective public health policy for controlling and mitigating the burden of emerging and re-emerging infectious diseases.
