Research Interests

I am interested in health at the human-wildlife interface, particularly where it pertains to conservation biology. I use methods in landscape ecology (GIS, remote sensing, spatial analyses), quantitative ecology and disease ecology to analyze landscape change, health outcomes and the impacts of anthropogenic change, including climate change, in African parks landscapes. I also use theoretical and statistical models to explore questions in disease ecology, community ecology and population biology, to augment field-based research.

My lab group is just starting out and will engage in interdisciplinary research, ranging from field biology to computational modeling to lab-based analyses of disease risk. My primary initial research concerns wild primate populations and health impacts both to and from human and domestic animal populations that they interact with.

Please contact me if you are interested in joining in!
