Paleoclimate and Stable Isotope Research

Broadly, I am a sedimentary and organic geochemist.  I focus on the redox evolution of the Earth, specializing in biogeochemical cycling.  I use a range of geochemical tools, but focus on the stable isotopes of nitrogen, carbon, and sulfur, with a particular interest in compound-specific, stable isotope techniques.  My research interests span the spectrum of geologic time from the Archean to modern systems.  Currently I am working principally on the Cretaceous and Neoproterozoic with an eye toward understanding future global change.
