Research Interests.

My students and I have an interest in wildlife management, conservation biology and ecology specifically related to 1) impacts of human activities on wildlife, 2) population ecology especially of small mammals, and 3) understanding patterns of species richness and our ability to predict species distributions across the landscape. To that end we have an interest in using state-of-the-art computer software in our work, including GIS and spatial modeling, with the ultimate goal of improving the management and conservation of wild species.
