Research Interests

I am a mathematical ecologist specializing in mathematical modeling of infectious diseases. My work has addressed multi-scale issues in a variety of infectious disease systems, including childhood immunizing diseases, influenza in wild birds and white-nose syndrome in bats. I am particularly interested in integrating dynamical systems theory and stochastic processes to model and analyze the dynamics of epidemiological and ecological systems that are close to a bifurcation.
