My primary work is documenting rates of mobile-regolith production with cosmogenic radionuclides(CRNs), and interpreting these data with numerical models of hillslope processes. In addition to hillslope research, I am also continuing work started by Miriam Dühnforth to document the timing of Quaternary terrace deposition and abandonment. I am using optically-stimulated luminescence (OSL) and cosmogenic radionuclides (CRN) to date these surfaces. In conjunction with absolute dating methods, I am also describing soils, performing soil texture analysis, and documenting pedogenic carbonate.

Models of 10Be on hillslopes require acknowledgement of transport within the mobile regolith
Cosmogenic radionuclide concentrations in hillslopes evolve by production, decay, and lateral transport of nuclides in regolith.
