Andy Cohen in the field


My research area is paleolimnology, the interpretation of lake history from sedimentary and paleontological records. Most of my work to date has involved studies of depositional environments, paleoecology, and climate history of the African Rift Lakes and the arid climate lakes of the western US. I use paleoecological and sedimentological records as primary tools in the interpretation of lake deposits, from both outcrops and sediment cores.

Research Projects

I currently have major projects in the following areas:Andy Cohen in the field

Additionally my lab has had recently completed projects in the following areas:


Normally, I teach the following classes:

  • GEOS 302-Principles of Stratigraphy and Sedimentology (Fall)
  • GEOS412-Ocean Science (Spring, with J. Cole)
  • 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.
