Biography

Ms. Wurstner joined PNNL as a full-time scientist in 1989. She is currently involved in simulating the injection and redistribution of CO2 in saline reservoirs to determine their suitability for Carbon Sequestration. Her other research interests include numerical modeling of groundwater flow and transport processes and migration of NAPLs, total systems risk assessments, Geographic Information Systems (GIS) and development of aquifer test analysis software. Ms. Wurstner is a licensed professional geologist and hydrogeologist in the state of Washington. She has previously served as adjunct faculty at Heritage College, in Toppenish, WA, and is currently serving as adjunct faculty at Columbia Basin College in Pasco, WA, and is active in various science education and outreach programs sponsored by the U.S. Department of Energy and Battelle. Ms. Wurstner received the 2002 Fitzner-Eberhardt Award for outstanding contributions to science and engineering education, and the 2004 PNNL Woman of Achievement Award.
