Research Interests :
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 projects are strongly interdisciplinary, including theoretical, empirical and model-based studies of the ecology of savannas and other semi-arid vegetation systems, the role of human management of grazing, fire and other disturbances in ecosystem dynamics, the use of micrometeorological techniques to study vegetation-atmosphere exchanges of carbon and water, and the use of remote sensing and geospatial datasets to measure and model ecosystem dynamics at landscape, regional and continental scales. Niall has published more than 70 peer reviewed scientific papers with research support from a variety of agencies (including ongoing or prior support from the National Science Foundation, NASA, USAID, National Geographic, Fulbright, Department of Energy, and NOAA).

Niall is a Professor of Dryland Ecology in the Plant and Environmental Sciences Department at New Mexico State University. After receiving a PhD in Biology (range ecology and remote sensing) from the University of London (Queen Mary College, 1990) Niall held post-doctoral appointments at the University of Maryland, in Wageningen (Netherlands) and at UC-Santa Barbara. Niall then joined the Natural Resource Ecology Laboratory (NREL) at Colorado State University where he spent 12 years as an Assistant, Associate and finally Senior Research Scientist studying the ecology of tropical and temperate savannas and drylands. In 2011 Niall moved to the Geospatial Sciences Center of Excellence at South Dakota State University where his research focused on remote sensing of tree-grass systems and the study of savannas and grazing lands as coupled social-ecological systems. He moved to NMSU in January 2017 where his research will focus on the ecology and management of drylands in the temperate grasslands and shrublands of the southwestern USA and in the tropical savannas of Africa and globally.
