Dr. DuPont's research interests cover welding metallurgy, failure analysis and product litigation, solidification, Laser Engineered Net Shaping (LENS), alloy development, and high temperature corrosion. He has published more than 200 technical articles, written one book, edited six books, and authored two book chapters. He holds one patent and has organized seven international conferences. His research programs are supported by the National Science Foundation (NSF), Department of Energy, Office of Naval Research (ONR), Knolls Atomic Power Laboratory, industrial consortia, and Defense Logistics Agency.

He is associate director of Lehigh's Energy Research Center and helped establish the Center for Integrative Materials Joining Science for Energy Applications. DuPont has won major awards from the NSF, ONR, American Society of Materials (ASM), and American Welding Society (AWS). In 2000, he received the NSF's Presidential Early Career Award for Scientists and Engineers from President Clinton, the highest honor bestowed by the U.S. government on scientists and engineers. He has also won awards from Lehigh for teaching and research.

He is a principal reviewer for Welding Journal, on the editorial board of Science & Technology of Welding and Joining, and a reviewer for Journal of Materials Engineering and Performance. He has served in several capacities for the ASM, and has served on the Edison Welding Institute Navy Joining Center Technical Advisory Board. Dr. DuPont is a fellow of the ASM and the AWS.
