Research interests

• Paleopedology, quaternary stratigraphy, sedimentology geology, hydrology, geomorphology, and paleoenvironments, including:
  • 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.
