Paleopedology, Quaternary Stratigraphy and Sedimentology
Director of Graduate Studies
Interests: Reconstruction of past landscapes and environments using data gleaned from physical and geochemical studies of deposits and soils. I use these reconstructions in a variety of applications including documenting rates of dust flux during the last glacial period, understanding conditions controlling the peopling of southeast Asia by hominins, landscape-scale geoarchaeology, and restoration strategies for rivers and streams.
