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
 Population Dynamics ( Conservation Biology; NativeInvasive Species competition: cottonwoodsalt cedar; Biological Pest Control )
 Disease Modeling ( Lyme Disease: Ticks and Hosts; Rabies in Raccoons;
Discrete Model; Antibioticresistant bacteria: Methicillinresistant Staphylococcus aureus (MRSA);
Modeling and Simulation of NFkB signaling for Parkinson's )
 Natural Resource Management ( Fisheries: General Population, Cod; NTFP: nontimber forest products; Optimal Plant Allocation )
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.
