He holds the Steve W. Chaddick Endowed Chair in Electro-Optics in the School of Electrical and Computer Engineering at Georgia Tech.
Dupuis was elected as a member into the National Academy of Engineering in 1989 for pioneering work in metalorganic chemical vapor deposition and demonstration of heterostructure devices.
He joined Rockwell International in 1975, where with P. Dan Dapkus, he was the first to demonstrate that MOCVD could be used for the growth of high-quality semiconductor thin films and devices such as lasers.
He moved to academia in 1989 to become a chaired professor at the University of Texas at Austin at the Microelectronics Center established by Ben G Streetman.
A Georgia Research Alliance Eminent Scholar, Dupuis and two of his colleagues were awarded the 2002 National Medal of Technology by President George W. Bush for their work on developing and commercializing LEDs.
