Brian Marshall
Brian Marshall is a Scientist Emeritus with the Geology, Geophysics, and Geochemistry Science Center.
Professional Experience
USGS Yucca Mountain Project Branch, Geochemistry Team Chief (2007-2010): Leader of team of geochemists and hydrologists responsible for defining, executing, and reporting on research for a variety of projects both externally and internally funded.
USGS Yucca Mountain Project Branch, Research Hydrologist/Geologist (1999-2007): Chemical and isotopic composition of pore water, rocks and secondary minerals in a thick vadose zone that is the proposed site of a nuclear waste repository. Responsible for formulating the research tasks, writing operating procedures, and publishing results, often with colleagues working on the same project.
