Edgar C Buck has been staff scientist V in the Radiochemical Processing Laboratory at PNNL since 2005. He manages several projects within PNNL’s Nuclear Processing Science Initiative to develop new advanced microscopy tools. He has been the program manager for a U.S. Department of Energy (DOE), Nuclear Energy project, supporting research for geologic disposal since 2009 and is principal investigator for a Counter-Weapons of Mass Destruction project on signature development, as well as several other smaller projects.

He has 70 publications and co-authored "Uranium," the third chapter for the 3rd edition of the Chemistry of the Actinide and Transactinide Elements. He has held other scientific leadership roles over time, including Actinide Migration and the Waste Form Corrosion projects.

Buck is knowledgeable in the interaction of electron beams with matter, electron and X-ray instrumentation, and materials science with an emphasis on radioactive materials. He has expertise in the long-term behavior of nuclear materials; including, spent nuclear fuels, borosilicate glass, radio-colloids, and post-irradiation examination of reactor components.

He was part of a team that was awarded the DOE Secretary of Energy Honor Award for work conducted on the Waste Isolation Pilot Plant accident in 2014, and was the lead author on the Waste Form and In-drift Colloids-Associated Radionuclide Concentrations: Abstraction and Summary, MDL-EBS-PA-000004 for the Yucca Mountain Repository License Application.

He has taught a graduate level course in electron microscopy at Washington State University (WSU) Tri-Cities and is currently adjunct professor at WSU.
