Mr. Wallace is the Radiological Technical Advisor at the Hanford Waste Tank Waste Treatment and Immobilization Plant (WTP). Prior to WTP, Ed served as a Senior Radiological Engineer at the Central Plateau Surveillance and Maintenance (CPSM) and the Central Radiological Control Group at CH2M Hill Plateau Remediation Company (CHPRC) from 2016-2018. Ed served as the Radiological Counting Facility Technical Lead, ISOCS Technical Lead and Radiological Measurements Subject Matter Expert for WCH from 2008-2016. During his 37 year career, he has practiced health physics in the radiopharmaceutical production, oil exploration and production and analytical laboratory industries as well as U.S. Department of Energy (US DOE) facilities and as a consultant to the Colorado Department of Public Health and Environment (CDPHE) Radiation Control Department.

Dan Strom earned BA and MS degrees in physics (UConn), and a Ph.D. (UNC Chapel Hill). His experience includes operational radiation safety, occupational radiation epidemiology, applied statistical inference, risk analysis, radiation detection, and graduate teaching and research in health physics, including 24 years at Pacific Northwest National Laboratory. He is currently adjunct faculty at the U.S. Transuranium and Uranium Registries. He’s a Certified Health Physicist, Fellow of the Health Physics Society, and Distinguished Emeritus Member of the National Council on Radiation Protection and Measurements. He was lead radiation protection design specialist at Ukraine’s Chernobyl New Safe Confinement (2011-2013).

George Tabatadze is an Assistant Director and Research Associate Professor in the U.S. Transuranium and Uranium Registries (USTUR) Research Center (https://ustur.wsu.edu/), College of Pharmacy and Pharmaceutical Sciences, Washington State University. He holds a B.S. in Physics and Computer Science from Tbilisi State University (Tbilisi, Georgia), M.S. in Health Physics (Medical Physics emphasis) from University of Nevada Las Vegas (Las Vegas, NV), and a Ph.D. in Applied Physics (Health Physics) from Idaho State University (Pocatello, ID). Dr. Tabatadze’s areas of expertise include radiation protection, radiation detection and measurement techniques, and radiation transport in the environment and human body. He is a past president of the Columbia Chapter of Health Physics Society (CCHPS).

Sergei Tolmachev is a Research Professor in the College of Pharmacy and Pharmaceutical Sciences, Washington State University, where he directs the U.S. Transuranium and Uranium Registries (USTUR) Research Center (www.ustur.wsu.edu). He holds a M.S. in Chemical Engineering from Mendeleev University of Chemical Technology of Russia (Moscow, Russia), and a Ph.D. in Chemistry from Kyushu University (Fukuoka, Japan). Dr. Tolmachev leads a team of multi-disciplinary scientists conducting long-term follow-up of former nuclear workers with accidental internal depositions of plutonium, americium, and uranium. His areas of expertise include radiation protection, environmental radiochemistry of actinides and polonium, radiation and mass-spectrometric instrumentation and measurement techniques. 

Dr. Walters received his Ph.D. in biophysics and radiation biology and has held a variety of senior management positions at the Los Alamos and Pacific Northwest National Laboratories.  After 9/11 he began serving the U.S. Intelligence Community in counter bioterrorism programs characterizing genomes of potential biowarfare pathogens, bioinformatics, and global biosurveillance.  For this work the National Intelligence Community awarded him (1) the National Intelligence Medal of Achievement for extraordinary technical leadership to prepare for and respond to acts of bioterrorism and natural disease outbreaks and (2) the National Intelligence Medallion for meritorious service in biosurveillance.
