Current Professional and Scholarly Interests

My research is in the broad field of Quaternary environments.  My students and I typically do extensive field work (or core analysis) involving fluvial sedimentology, paleoclimatology, land-use studies, and geoarcheology.  Examples of recent projects include the following:
