Dr. Niall Hanan is a 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. His on-going research includes studies of coupled ecohydrological and social systems in semi-arid grazing lands, carbon cycle measurement, remote sensing and modeling, and studies of changing patterns of land use, access to resources and social conflict in agricultural and pastoral communities of West Africa.  Hanan’s research is currently supported via grants from the US National Science Foundation (NSF), NASA and the US Agency for International Development (USAID). Earlier sponsors have included the Department of Energy (DOE), NOAA, National Geographic Society, and others. Hanan completed undergraduate and graduate degrees in Liverpool and London (UK), respectively.
