Vitae:

Dr. DuPont graduated Cum Laude with a B.S. Degree in Metallurgical Engineering from Ohio State University and with M.S. and Ph.D. Degrees in Materials Science and Engineering from Lehigh University . He was a Research Scientist and Associate Director of the Energy Liaison Program at Lehigh University until 1999. He joined the Materials Science and Engineering Department as Assistant Professor in 1999 and was promoted to Associate Professor in 2002. His research interests cover processing-microstructure-property relations in solidification and joining of materials, Laser Engineered Net Shaping, and alloy development. His research results have been published in over 170 technical articles. He teaches courses in Introduction to Materials, Diffusion and Phase Transformations, Materials Selection, Failure Analysis, Welding Metallurgy, and Advanced Solidification. He has edited four books, co-authored one book chapter, has one patent, and has organized four 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, 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 AWS National Fellowship Award in 1995. He was twice the recipient of the AWS Harold H.

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. The award was presented for “initiating a highly collaborative and interdisciplinary education and research effort in manufacturing using Laser Engineered Net Shaping (LENS) processing”. 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 recently 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.

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. He has served as a consultant to industry and government research laboratories. Dr. DuPont has also developed and taught industrial short courses in the areas of welding, failure analysis, metallurgy for the non-metallurgist, and heat treating.
