Research Interests and Current Projects

My research interests are in arid zone soils, specifically, genesis and biogeochemical cycling of soils in desert mountains.  I am interested in quantitatively describing soil morphology, relating these variables to landscape processes, and applying numerical models to study pedological phenomena. This research will help to understand soil-landscape response to past and future environmental conditions. More information available here.
