Marion Russell has been working at Lawrence Berkeley Lab since 1996 and currently manages an analytical laboratory in the Energy Analysis and Environmental Impacts Division. Marion collaborates with scientists and engineers in the division to develop methods for collecting and measuring trace levels of pollutants in air samples with the goal of mitigating and reducing human exposure. Our lab is equipped with a broad range of tools that enable experiments and testing in controlled chambers to extensive field studies. She enjoys mentoring student assistants and volunteering as a high school cycling coach. Marion earned her M.S.degree in Chemistry from the University of Indiana, in Bloomington, Indiana.
