Roger is a member of the Energy and Environment Directorate at Lawrence Livermore National Laboratory, where he leads the geochemistry group. Roger holds a Bachelor of Arts degree in Chemistry from Carleton College, and Doctor of Philosophy in geochemistry from the California Institute of Technology.

Roger’s research interests include the in situ degradation of organic chemicals through heating, simulation of steam-driven underground processes in heterogeneous media, and the mechanisms of thermally-assisted remediation. A key research area for Roger has been the coupling of active remediation methods to longer-term, self actuating methods like oxidation and bioremediation. With large masses of NAPL removed, these mechanisms can be dependable ways to ensure safe closure. A co-developer of Dynamic Underground Stripping and Hydrous Pyrolysis/Oxidation, he supports the application of thermal remediation techniques at both private and government site cleanups by serving on a number of Federal and private review panels, and as the LLNL technical lead for the DOE Subsurface Technical Support Teams. He has been involved in design and operation of the Visalia site, a prime example of the difficult issue of defining end points.
