My research is largely devoted to documenting and understanding past climates, especially in the North Atlantic Ocean during the last millennium. Additionally, I am interested in developing new geochemical tools and proxy records for paleoceanographic applications. For my research, I primarily utilize light stable isotopes in biogenic carbonates. I am an active sclerochronologist who mostly works with mollusks. I also direct the Stable Isotope Laboratory in the Department of Geological and Atmospheric Sciences.

Area of Expertise: Climate Change, Paleoclimate, and Stable Isotope Geometry
