Research Focus

I am a quantitative ecologist, and I work at the interface of empirical and theoretical ecology. I use statistics, often custom designed, to link mathematical models of the systems I study to data. I then use the results of that linkage—a parameterized model of the focal system—to answer both basic and applied questions. My general approach is to work collaboratively with experts on the particular systems I study to help forge a stronger connection between the theoretical and empirical sides of the problem.
