(Associate Professor)

 

 

The general focus of my research is on the application of stable isotopes to geochemistry and cosmochemistry.  Support for this research comes from NSF, NASA, and the American Chemical Society.  A large part of my research focuses on the application of multiple isotope fractionation effects to the study of :

 

• Atmospheric evolution (terrestrial samples and SNC/Martian meteorites)

 

• Atmospheric deposition (environmental studies of nitrate and sulfate)

 

• Studies of the cosmochemistry (evolution of water early in solar system )

 

• Developing tools to investigate the antiquity of biological processes

 

• Developing tools to investigate the flow of sulfur through geological, biological, and sedimentary systems

 

• Experimental studies of photochemical mass-independent isotope effects
