Research profile

I am a geographer, working on sustainable agriculture/managed ecosystems and climate in Africa. After my PhD at Clark University in the northeastern US, I undertook a NOAA Global & Climate Change postdoctoral fellowship at the International Research Institute for Climate Prediction (IRI) at Columbia University in New York; co-hosted by the Pennsylvania State University.  My research focus is on drylands, with experience throughout the SADC region and on the continent.  I have served as the co-chair for the Intergovernmental Panel on Biodiversity and Ecosystem Services Africa Assessment (www.ipbes.net), as a Coordinating Lead Author (CLA) on the Forests and Water Assessment of the Global Forestry Expert Panels (GFEP).
