Land-atmosphere interaction, climate-vegetation modeling, and catchment hydrology

My primary research interests are in the areas of (1) catchment hydrology, focusing on hydrological and geochemical transport processes, and (2) land-atmosphere interaction, including the exchange of water, energy, and gaseous compounds such as carbon dioxide, nitrous oxide, and methane between the terrestrial surface and the atmosphere. I seek to develop an integrated understanding of how the hydrological cycle, vegetation processes, and atmospheric dynamics are linked as well as how these connections are manifest in terms of nutrient cycling and ecosystem function. My research combines a balance of field, remote sensing, and numerical modeling methods to address these issues over a broad range of spatial and temporal scales. Current field locations for my research include Shenandoah National Park, Ireland, and southern Africa.
