Brian Marshall is the manager of the Geochemistry Lab in the Energy Resources Science Center. He has been with the USGS since 1984, applying isotopic and chemical measurements to problems in hydrology, waste disposal, geochronology, and igneous petrology. He earned a Ph.D. in Geochemistry from UCLA in 1984 and a B.S. in Geology from the University of California at Davis in 1979.
