Burton M. (Mack) Kennedy

geochemist: Earth and Environmental Sciences

Media contact: Dan Krotz, 510-486-4019,


As the Group Leader for the Center for Isotope Geochemistry and the Program Lead for Geothermal Energy Development, Mack Kennedy applies isotope techniques to further our understanding of the origin, history, and current processes acting on the earth and solar system.  

Specifically, noble gas isotope geochemistry as applied to sources, geochemical evolution, transport processes, and flow rates of fluids in the crust, cosmogenic and radiometric dating techniques, tectano-magmatic processes, and paleoclimatology.  Research areas of application include geothermal energy, fossil energy, and basic energy sciences.
