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.

I currently have major projects in the following areas:

- The Hominin Sites and Paleolakes Drilling Project: Studying the Implications of African Paleoclimates and Paleoenvironments for Understanding Human Evolution
- Paleoclimates and Paleolimnology of Lakes in the US Great Basin
- East African Paleoclimate and Ecosystem History
- Lake Malawi Drilling Project
- Paleorecords of Watershed Deforestation and Recent Climate Change

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

- Deposystem Evolution in the Foreland Basin Lakes of South America
- Nyanza Project REU training Program (concluded 2007)
