Group: EES-DO  

Expertise

Andrew is the Group Leader for Computational Earth Science in the Earth and Enviromental Sciences Division at LANL. He manages R&D staff addressing problems and developing capabilities in subject areas including subsurface flow and contaminant transport, radioactive waste disposal concepts, subsurface CO2 sequestration, geologic characterization and mapping, geographic information systems, basin-scale surface hydrology and integration with energy development, energy utilization and development impacts, regional climate, wildfire, urban firestorms, hurricanes, space weather, and electromagnetic pulse transport.

Andrew currently (2010, 2011) serves as the LANL laboratory lead for the multilab DOE program for Advanced Simulation Capability for Environmental Management (ASCEM).
