Chris Graham Post Doc.

      I am interested in subsurface flow processes, from the pedon to catchment scale. I am working on bridging the gap between the experimentalist and modeling communities, by developing simple, conceptual based models based on field experimentation designed to determine the dominant flow processes operating at the hillslope scale. My background includes both the field experimentation and numeric modeling sides of this problem. Currently, I am working at the Shale Hills Critical Zone Observatory, bringing a catchment modeling approach to the hydropedological work currently performed by Dr. Lin’s group.
