Our research program studies the earth surface including chemical weathering, soil formation, and biogeochemical cycling.  We focus on soil processes, also known as the Critical Zone: that area of the earth's surface where lithosphere, hydrosphere, biosphere, and atmosphere intersect.    We use isotopic and trace element geochemistry to understand how these processes impact landscape evolution, global elemental cycles, and ecosystem productivity.
