Research Interest

community and ecosystem ecologist with particular research interests in the ecological and biogeochemical dynamics of tropical and temperate grasslands and savannas. He approaches these subjects at a range of spatial and temporal scales, from detailed plot-based experimentation, to landscape-scale observations, to landscape, regional and continental scale remote sensing and modeling.
