My graduate students and I study wildlife ecology and management in a variety of landscapes, with a strong focus on habitat and populations. Primary field tools we use include wildlife capture, human dimensions surveys, population abundance surveys, radiotelemetry, remote cameras, and vegetation sampling. In the analytical laboratory, we work with GIS, multivariate statistics, and a variety of software programs useful for analyzing demographic and space-use data. I also frequently collaborate with behavioral ecologists, geneticists, and other wildlife ecologists who add a greater dimension to my work.
