Faculty Overview

Dr. Brian A. Powell has expertise in the understanding and prediction of the physical, chemical, and biological processes which govern the mobility of radionuclides in natural and engineered systems through his research in the Department of Environmental Engineering and Earth Sciences at Clemson University as well as previous work at the Lawrence Livermore National Laboratory and the Lawrence Berkeley National Laboratory. He has a B.S. in Chemistry from the University of Montevallo, and M.S. and Ph.D. in Environmental Engineering and Science from Clemson University. He holds memberships in the American Chemical Society, American Geophysical Union, Geological Society of America, Association of Environmental Engineering and Science Professors, and Sigma Xi. At Clemson University, Dr. Powell teaches courses in Actinide Environmental Chemistry, Environmental Radiation Protection (Lecture and Laboratory courses), Introductory Health Physics, Geochemistry, and Geochemical Reaction Modeling.

His research focuses on biogeochemical processes controlling radionuclide behavior in the environment such as sorption by minerals, interactions with nano-colloids, complexation by organic ligands, and interactions with microorganisms. He has published over 30 refereed journal publications,16 research reports, and made over 50 technical presentations on these topical areas. He has conducted sponsored research in a wide range of projects dealing with topics of nuclear forensics, evaluation of nanoparticle behavior, sorption and environmental transport of plutonium, development of radiation detection and radiation detection laboratory courses, iodine, radium, strontium geochemistry in wetland and subsurface sediments, radionuclide geochemistry of saltstone and solid waste performance assessments at the Savannah River Site, measurement of thermodynamic parameters supporting advanced fuel cycle chemistry, and related topics. These research projects have received over $6M in funding from the National Science Foundation, the Department of Energy, the Nuclear Regulatory Commission, the Department of Homeland Security, the National Nuclear Security Agency, and Savannah River Nuclear Services (through the South Carolina Universities Education and Research Foundation). The knowledge gained from this work can be used to evaluate risk posed by subsurface contamination, to design remediation strategies for contaminated sites, and to facilitate the use of safe disposal practices.

Professor Brian Powell is the Principal Investigator on the Department of Energy, Experimental Program to Stimulate Competitive Research Implementation Project "Radionuclide Waste Disposal: Development of Multi-scale Experimental and Modeling Capabilities" (2014-Present)
