Research interests


I am interested in the exchanges of energy, water and carbon dioxide at the soil, vegetation, and atmospheric interface and the interactions between hydrology and ecology.  I focus on these exchanges and interactions in water-limited areas.  Some of my specific research topics include: 1) the consequences of global environmental change on water and carbon cycling, 2) improving estimates and models of riparian vegetation water use, 3) determining the role that vegetation plays on vadose zone soil water redistribution, and 4) partitioning evapotranspiration and carbon dioxide fluxes into their component fluxes.
