My research area is paleolimnology, the interpretation of lake history from sedimentary and paleontological records. Most of my work and that of my students involves studies of paleoecology, depositional environments, climate and environmental history of the African Rift Lakes and the arid climate paleolakes of the western US. I use paleoecological and sedimentological records, particularly from ostracode crustaceans, as primary tools in the interpretation of lake deposits, from both outcrops and sediment cores.

Active Research Projects

I currently have major projects in the following areas:

Normally, I teach the following classes:

  • GEOS 302-Principles of Stratigraphy and Sedimentology (Fall)
  • GEOS 308-Paleontology (Spring, with Kau Thirumalai)
  • GEOS 596D-Seminar. I offer seminars annually (usually in the spring semester) in paleolimnology, alternating every other year with more specialized subjects to be announced.
