Research interests

 

I am interested in the exchanges of energy and mass (primarily, 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 change on water and carbon cycling in semiarid areas, 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 fluxes into their component fluxes.
