Research Interests

Climate and ocean history using oxygen and carbon isotopes in foraminifera, biostratigraphic techniques, and sediment lithology; specific interests include: circulation history of the pre-Quaternary ocean on orbital time scales; history of climate and ocean circulation change in the Holocene and late Pleistocene on millennial and century time scales; relationship between the ecology of living benthic foraminiferal species and their stable isotope composition.
