Research

My research interests are energy and mass transfer at the land-atmosphere interface.  I have experience in the design and evaluation of enclosure (chamber) techniques for measurement of trace gas fluxes between soils and atmosphere.  I am also interested in the application of thermal imagery, eddy covariance, micro-lysimeter, and sap flow gauge techniques in study of evaporation and transpiration processes.
