I teach graduate courses at Tarleton State University, Stephenville, TX 76401. I mentor MSc & PhD students at various universities around the world. My research program focuses on grassland ecology, mostly at the plant-animal interface, with special emphasis on legumes. Topics include grassland restoration, ecosystems services, native legume domestication and the role of condensed tannins in ruminant systems.
I have current cooperative research projects in Tanzania, Botswana and Brazil. In the past I have worked extensively in Kenya, Senegal, South Africa, Malawi, Argentina and Portugal.
