Research Interests

Ecology, Infectious Disease Dynamics, and Theoretical and Computational Biology

I am a theoretical ecologist working as a professor in the Departments of Entomology and Biology. My main interests are population ecology and population dynamics with particular emphasis on mathematical and computational aspects. I am also an adjunct professor in the Department of Statistics, and carry out research in statistical ecology and in methods for analyzing spatiotemporal data.
