Research Interests:

My research interests include mathematical biology, optimal control, mathematical modeling, ordinary and partial differential equations, difference equations and hybrid systems with applications to

Mathematical biology is a growing branch of applied mathematics as the interest of modeling complex biological systems increases. Optimal control theory is a branch of mathematics developed to find optimal ways to control a dynamic system. Generally, the optimal control problem consists of an objective functional, a dynamic system and the control(s). The controls enter the dynamics in a variety of ways as coefficients, boundary terms or sources.

My research focuses on understanding the spatial and temporal patterns that arise in dynamic biological systems and when possible, finding the best way to control the system.

Science Feb. 6th, 2004 --- Devoted to Mathematics in Biology

In a special collection of articles published beginning 6 February 2004, Science Magazine and its online companion sites teamed up to explore one of the hottest interdisciplinary collaborations in science today: the interface between mathematics and biology. In Science, News, Viewpoint, and Review articles covered how mathematics and computation are informing biology on a wide variety of fronts, the need for incorporating quantitative approaches into bioscience curricula, and some of the uses -- and abuses -- of mathematical models for biological systems.
