Research Interests

We work on ecology at the human interface and its implications for conservation, sustainability, wildlife management, and disease ecology.

Our interdisciplinary work incorporates tools from quantitative and applied ecology, geography and social science. We use techniques from the lab to the field to the computer to the white board.

We play well with others, and welcome collaborations.
