Current interests include both the measurement and modeling of energy and carbon fluxes and the interactions of these fluxes between the land surface and boundary layer with an overall goal to improve the representation of the earth surface and boundary layer interactions in both weather and climate models. This research can play a major role in helping communities to adapt and be more resilient to a changing climate and associated extreme events.
