Research Interests

I am a community ecologist with broad research interests, including species coexistence, the ecology and evolution of mutualisms, and the role of ecosystem engineers in structuring rangeland communities. Most of my work is conducted in East Africa, although I have also worked in alpine streams, meadows and prairies of the western U.S. My current projects include 1) long-term studies of species coexistence in a guild of African acacia ants, 2) costs, benefits and conditionality within a multi-species ant-plant mutualism, 3) a large-scale exclosure project examining the influence of different guilds of large African mammals on biodiversity and productivity within semi-arid rangelands, and 4) the role of termites in structuring African savannas and bushlands. These projects are funded by the National Science Foundation. More detail on these projects can be found on my personal site.
