Hilary I. Inyang is the Duke Energy Distinguished Professor of Environmental Engineering and Science, Professor of Earth Science and Director of the Global Institute for Energy and Environmental Systems at the University of North Carolina-Charlotte. Prior to his current position, he was University (titled) Professor, Dupont Young Professor and Director of the Center for Environmental Engineering, Science and Technology (CEEST) at the University of Massachusetts, Lowell. Previously he taught at George Washington University, Washington, D.C; Purdue University, West Lafayette, Indiana; and University of Wisconsin, Platteville. Prof. Inyang also served at the U.S. Environmental Protection Agency (1991-1993) as a Senior Geoenvironmental Engineer and subsequently as the President of Geoenvironmental Design and Research (GDR) Inc., Fairfax, VA, a small research firm that he founded in 1993. His research and allied professional activities have focused on waste containment systems, contaminant leachability, soil/contaminant physico-chemical interactions, natural disaster mitigation techniques, rock fragmentation techniques for energy installations and underground space, and energy/environmental policy. His projects have been sponsored by federal agencies such as US. Department of Defense, U.S. Environmental Protection Agency, U.S. Department of Agriculture, National Oceanic and Atmospheric Administration, Federal Highway Administration, the United States Agency for International Development, and corporations such as Duke Energy Corporation, and Dupont Corporation. Through basic and applied research, associated technical activities, advisory roles in state, national and international government agencies, and education, Prof. Inyang has made significant contributions to the evolution of the new field of geoenvironmental engineering. He has authored/co-authored more than 140 research articles, book chapters, federal design manuals and the textbook- Geoenvironmental Engineering: principles and applications.
John Daniels is an Assistant Professor in the Department of Civil Engineering and a Faculty Associate in the Global Institute for Energy and Environmental Systems at the University of North Carolina at Charlotte, USA. Recent research has included improvement of barrier material resistance to freeze-thaw and desiccation stress with aqueous polymer solutions, funded in part by the U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory and the Clay Minerals Society. He has also worked on research funded by the DuPont Company to enhance the heavy metal attenuation capacity of slurry wall materials. Other research interests include improving the efficiency of geothermal energy extraction through assessment of soil thermal conductivity. His professional activities include membership with the American Society of Civil Engineers, National Society of Professional Engineers, Solid Waste Association of North America, and Clay Minerals Society. He has worked for TRC Environmental Corporation, Lowell, MA as a project engineer and is a registered professional engineer (PE) in the Commonwealth of Massachusetts and the State of North Carolina. He holds a Bachelor of Science degree in Civil Engineering from Lehigh University, Bethlehem, PA; a Master of Science degree in Civil Engineering and a Doctor of Engineering degree in Civil Engineering from the University of Massachusetts, Lowell, MA
