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.
