Timothy D. Comar is a professor of mathematics at Benedictine University in Lisle, IL.  He earned his Ph.D. in mathematics at the University of Michigan specializing in low dimensional topology. He is currently working mathematical biology with interests in the dynamics of deterministic and stochastic models for pest management, vaccination strategies for epidemics, and gene regulatory networks using impulsive differential equations, difference equations, Boolean models, and agent-based models.  He has taught biocalculus courses for many years, and mentored many undergraduate research projects in mathematical biology.
