Our lab is involved in mathematical modeling physical soil processes, simulation of mass and energy flows in soil, and statistical modeling of near-surface soil moisture dynamics.   Mass and energy fluxes in dry-hot areas are strongly coupled and have strong bearing on delicate ecosystems of such areas. We work with collaborators at Desert Research Institute to understand coupling between soil moisture and atmospheric variables. We are woking on analysis and simulation of long-term soil and atmospheric data collected at a lysimeter facility.
