Russell Dean Dupuis (born 9 July 1947) is an American physicist. He holds the Steve W. Chaddick Endowed Chair in Electro-Optics in the School of Electrical and Computer Engineering at Georgia Tech. He has made pioneering contributions to metalorganic chemical vapor deposition (MOCVD) and continuous-wave room-temperature quantum-well lasers. His other work has focused on III-V heterojunction devices, and LEDs. 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.
