Area of Interest

Sedimentary and Environmental Geology


My research centers on the controls on, and the impacts of, sedimentation in continental settings. Presently, the research I do falls within two different themes:  1) Documenting recent sedimentation in African lakes and its impacts on biologic and human systems, and 2) Interpreting long-term climatic signals from late Paleozoic eolian and lacustrine strata. Please visit the link below (personal web page) to read about specific research projects and how students can be involved. My main research methods lie in field-oriented data collection, however, I have increasingly employed geochemistry, computer imaging and modeling to supplement the field data. My research has mainly been funded by the National Science Foundation, however, work in East Africa has also been supported by the National Geographic Society and The Nature Conservancy.
