Research interests: Factors controlling the isotope composition (13C, 14C, 2H, 15N, 34S) of organic materials in marine environments; construction of ancient conditions (pCO2, trophic structure) from isotopic compositions of organic compounds in sediments; development of the global carbon cycle over geologic time; techniques of isotope analysis.

Urey Medal: The 1997 Urey Medal for lifetime achievement is shared by Dr. John M. Hayes, Woods Hole Oceanographic Institute, and Dr. Geoffrey Eglinton, University of Bristol. Dr. Hayes is recognized for his outstanding contributions to biogeochemistry, including the application of light stable isotope studies and innovative mass spectrometry developments. Dr. Eglinton is recognized for his pioneering work in organic geochemistry and the development of a method to determine paleotemperature.

Please, be prepared to give me a time during which you will meet with our visiting speaker.
