Dr. Allen Shapiro is a Senior Research Hydrologist with the U.S. Geological Survey (USGS). He is a member of the Water Cycle Branch in the Earth System Processes Division (ESPD) of the Water Mission Area (WMA). Dr. Shapiro conducts research on groundwater flow and chemical transport in complex geologic environments, including fractured rock and karst aquifers. Dr. Shapiro's research has focused on the development of field techniques and equipment, modeling groundwater flow and chemical transport, and methods of integrating and interpreting geologic, geophysical, hydraulic, and geochemical information in characterizing fractured rock aquifers. Dr. Shapiro is also actively pursuing research in the characterization and remediation of various contaminants in fractured rock, including chlorinated solvents and other Dense Non-Aqueous Phase Liquids. He is a graduate of Princeton University with a Ph.D. in Civil and Geological Engineering. He has been an Adjunct Professor in the Department of Earth and Environmental Sciences at Columbia University. Dr. Shapiro is a Fellow of the Geological Society of America, and in 2004, the National Ground Water Association selected him as the Distinguished Darcy Lecturer, Dr. Shapiro has also served on National Research Council panels that have produced extensive reports on key engineering and scientific issues facing the Nation.

Sophia Lee, PG, Naval Facilities Engineering and Expeditionary Warfare Center (
Sophia Lee is a project manager and hydrogeologist for the Navy Facilities Engineering Command's Expeditionary Warfare Center (NAVFAC EXWC). While only recently joining the NAVFAC family, she previously spent 8 years working as a consultant in Denver and Boulder, CO. Her experience in the design, construction, and calibration of both regional and site-specific MODFLOW models has helped her to develop the opinion that when it comes to modeling, the "Less is More" philosophy is usually apt for assessing most groundwater problems. In addition to groundwater modeling, Ms. Lee has also been involved in well installation and aquifer testing of groundwater wells for both remote and urban environments. Ms. Lee received her undergraduate degrees in Geology and Classical and Near Eastern Archaeology from Bryn Mawr College and her Master's in Hydrological Sciences and Engineers from the Colorado School of Mines. She is currently a member of the Environmental Restoration team and supports groundwater remediation and supply projects for the Navy throughout the world.

Dr. Haruko Wainwright is a research scientist at Lawrence Berkeley National Laboratory. She earned a Master in nuclear engineering and statistics, and PhD in nuclear engineering at the University of California, Berkeley. Her research focuses on hydrological modeling, spatial statistics, data integration, and uncertainty quantification. She has worked on various research topics in both nuclear engineering and environmental sciences, including nuclear waste, groundwater contamination, Fukushima radiation monitoring, and climate change impacts on ecosystems.
