    Headshot Stauffer

    Dr. Philip Stauffer is a Senior Scientist in the Earth and Environmental Sciences Division at Los Alamos National Laboratory. He received a Ph.D. in Geosciences (Hydrogeology) from the University of California, Santa Cruz in 1999. Stauffer is a co-developer of the subsurface flow and transport code FEHM. Stauffer is a lead investigator for the Low Yield Nuclear Monitoring Program (NA22) involved in simulating new experiments at the Nevada National Security Site (NNSS formerly NTS) exploring how radioactive gases escape from underground nuclear explosions.

    Stauffer has over 30 years experience in radioactive waste management simulations, both locally at the Los Alamos site and more broadly as part of the DOE's high-level waste program. Stauffer has over 20 years of experience in CO2 sequestration simulations and was a lead developer of the first generation of the National Risk Assessment Partnership Integrated Assessment Model (NRAP-IAM). Collaborations with universities have allowed Stauffer to explore gas flow on Mars, sea-floor convection, and volcanic hydrothermal systems.
