My research focuses on the basin analysis of extensional systems, with emphasis on lacustrine rift basins. Current research and field programs are concentrated in the East African Rift Valley and the Baikal Rift of Siberia. The world's large rift valley lakes are outstanding laboratories for understanding the interaction of tectonic, climatic, and depositional processes, and are particularly useful for developing models for hydrocarbon exploration in ancient rift systems. These large, deep lakes contain thick accumulations of sediment dating back millions of years, and are among the highest quality archives of climate change on the continents.
Field programs commonly involve the acquisition of seismic reflection datasets and sediment cores from the rift valley lakes.
Support for the research comes from the National Science Foundation and from the Rift Basin Industrial Associates, a consortium of eight oil and gas companies.
