Prof. DuPont is currently the R.D. Stout Distinguished Professor of Materials Science & Engineering at Lehigh University. He is also Associate Director of Lehigh’s Energy Research Center, holds a joint appointment in the Mechanical Engineering Department, and is the Site Director for the National Science Foundation Manufacturing and Materials Joining Innovation Center. Prior to obtaining his formal education, Dr. DuPont earned a Diploma in Welding, a Certificate in Welding Technology, and worked as a certified welder in a variety of fabrication facilities. His current research, teaching, and consulting activities cover areas of welding metallurgy, failure analysis and product litigation, solidification, Laser Engineered Net Shaping, alloy development, and high temperature corrosion. He has published over 300 technical articles in these areas. He teaches courses in Welding Metallurgy, Failure Analysis, Introduction to Materials, Diffusion and Phase Transformations, Materials Selection, and Advanced Solidification. He has written one book, edited seven books, authored four book chapters, has two patents, and has organized seven international conferences in these areas. His research programs are supported by a variety of organizations, including National Science Foundation, Knolls Atomic Power Laboratory, Office of Naval Research, industrial consortia, Defense Logistics Agency, Department of Transportation, and Department of Energy (including DOE Fossil Energy Materials Program, DOE National Spent Nuclear Fuel Program, DOE University Coal Research Program, and DOE Industries of the Future Program).

Prof. DuPont was an ASM scholar in 1990 and received an American Welding Society (AWS) National Fellowship Award in 1995. He was the recipient of the AWS Harold H. Jennings Award in 1996 and 2000 and the AWS William Sparegan Award in 1999, 2000, 2008, and 2010 for the best research paper written in the Welding Journal. He received the A.F. Davis Silver Medal Award from AWS in 2001, 2002, and 2004 and the Warren F. Savage Award in 2004. In 1999 he was awarded the AWS Prof. Koichi Masubuchi Award, which is sponsored by the Massachusetts Institute of Technology and made to “the outstanding scientist under the age of 40 who has made significant contributions to advance the science and technology of welding materials through research and development”.  In 2000, he received a Young Investigator Award from the Office of Naval Research for work on laser welding of super austenitic stainless steels in advanced double hull combatant ships, and a CAREER award from the National Science Foundation for research on Laser Engineered Net Shaping. In October of 2000, Dr. DuPont received the National Science Foundation Presidential Early Career Award for Scientist and Engineers (PECASE) from President Clinton, which is the highest honor bestowed by the US government on outstanding scientist and engineers. In 2002 he received the AWS Adams Memorial Award for outstanding teaching activities at the undergraduate and post-graduate level and in 2003 received the Lehigh University College of Engineering Teaching Excellence Award. Dr. DuPont was named a Fellow of the American Society for Materials in 2006 and received the Lehigh University Eleanor and Joseph F. Libsch Early Career Research Award for recognizing faculty for high quality research in their career. Dr. DuPont was awarded the American Welding Society William Irrgang Award, which is presented to the individual who has done the most to enhance AWS’s goal of advancing the science and technology of welding and joining over the last five years. In 2007, he was awarded the Bradley Stoughton Award of the Lehigh Valley Chapter of ASM International, which is given to an individual for outstanding contributions to metallurgy and/or materials science and engineering, and is the most prestigious award given by the Chapter. He was elected a Fellow of the American Welding Society in 2008. He was recently selected to receive the 2013 AWS Comfort A. Adams Memorial lecture, which is the highest technical award made by AWS. IN 2015 he was awarded the Department of Defense Manufacturing Technology Achievement Award for project entitled “Welding of High Strength Steels”. This award recognizes and honors individuals most responsible for outstanding technical accomplishments that further the achievement of the vision of the Department of Defense Manufacturing Technology Program.

Dr. DuPont is currently a Principal Reviewer for the Welding Journal, on the editorial board for the Science & Technology of Welding and Joining, and a reviewer for the Journal of Materials Engineering and Performance. He is a past Chairmen of the American Society for Materials (ASM) Committee on Fusion Welding, past Vice Chairman of the ASM Committee on Joining, on the AWS Awards Committee, the AWS Research & Development Committee, the AWS Handbook Committee, the AWS Conference Committee, the AWS Technical Papers Committee, and the Edison Welding Institute Navy Joining Center Technical Advisory Board.
