His research revolves around the study of solid surfaces with focus in experimental model systems for heterogeneous catalysts. Specifically, he pioneered the development of surface science models for zeolites, the most used catalysts in the industry, while working at the Fritz Haber Institute of the Max-Planck Society in Berlin, Germany. His current research at the Center for Functional Nanomaterials focuses on experimental models for zeolites and other catalysts aiming at elucidating the reaction mechanisms for catalytic processes of importance for energy transformations. At Brookhaven National Laboratory, he is in charge of the Ambient Pressure Photoelectron Spectroscopy endstation, in partnership with the National Synchrotron Light Source II. He received his bachelor’s in chemistry from University of San Luis, Argentina, and doctorate in chemistry from the University of Wisconsin-Milwaukee, followed by postdoctoral research at the Fritz-Haber Institute of the Max-Planck Society under the auspices of the Alexander von Humboldt Foundation.
Dr. Wellons is a principle scientist in the National Security Directorate at Savannah River National Laboratory (SRNL). He received his Ph.D. in Chemistry from Vanderbilt University in 2008 and has almost a decade of experience working on safeguards and nonproliferation topics within the USG. His general area of research expertise has primarily been method development in support of nuclear material characterization R&D and analytical operations. This has included development of new microscopy and spectroscopy techniques to characterization uranium materials, research into the chemical stability of actinides materials in the environment, and the development of actinide reference particles for safeguards. He has an extensive background in many experimental techniques and methods, with a focus on microanalytical techniques (various scanning and transmission electron microscopy and diffraction methods, and Raman and IR spectroscopy). He also has extensive experience with field campaign development and execution for the collection of trace materials from the environment. Dr. Wellons has published 20+ journal articles in refereed journals, given multiple invited lectures, and garnered two patents on variety of topics including several material science topics, safeguards technologies, and actinide material characterization method development.
After graduating from the University of Florida in 2004 with a Bachelor’s degree in chemistry, Dr. Aaron L. Washington, II completed his PhD in Inorganic Chemistry with specialization in material science. As of April 2009, Dr. Washington joined the Advanced Characterization and Processing (ACP) group at SRNL and is currently a principal scientist and former manager in the same group. He is currently involved with material development for multiple applications including radiological sensors, nuclear waste storage, additive manufacturing for nuclear material disposal, nuclear Deactivation & Decommissioning (D&D), organic based nuclear sensors, and nuclear waste treatment strategies. Additionally, he recently led a group with 3 post-doctoral researchers (3 former postdocs are now full time), 7 peer PhD scientists, a bachelor’s scientist, 3 managers, and 2-4 interns in interdisciplinary research and program development. Dr. Washington has more than 20+ peer reviewed manuscripts, 30+ technical reports, and more than 15 presentations at national conferences and meetings. Dr. Washington also has 4 patents issued and 7 additional patents currently in process. Dr. Washington was a 2014 recipient of the Laboratory Director’s Award for Early Career Exceptional Achievement and the 2016 Laboratory Director’s Award for Exceptional Achievement. Dr. Washington has also recently received his Project Management Professional (PMP) certification as of July 2017.
Dr. Washington currently serves on multiple committees both at SRNL and in the Aiken community. These include the Conduct of R&D safety council, Diversity Board of Directors for SRNS, and the former Board of Directors Chairman and current member for Habitat for Humanity. He is an also an Adjunct Professor at USC Aiken in the chemistry department.
