I combine empirical data, fieldwork, and quantitative methods to address applied problems. My focus is broad, extending from understanding how to assess the spatial extent and ecological consequences of wildlife overexploitation, to fisheries management, the ecology and conservation of predators, disease ecology and population dynamics in a changing climate. In each case, humans have altered ecological interactions with consequences for things that we care about, which is where management options need to be considered. Although my work is rooted in ecology and applied mathematics, I like to cross disciplinary boundaries to explore implications for human livelihoods and health. I currently work in Amazonia, Alaska and the deciduous forests of New York. Quantitative wildlife ecology and conservation, community ecology, disease ecology, tropical wildlife ecology.
