Biographical Sketch

Dr. M. A. Wahab earned a 鈥淢aster of Science in Engineering鈥� from the University of New Brunswick, Canada and a PhD in Mechanical Engineering from the University of Alberta, Edmonton, Canada in 1984. Afterward he moved to Australia and worked as a Faculty in Mechanical Engineering from 1985 to 2001 at four different Australian universities (RMIT University- Melbourne, University of Tasmania-Hobart, Central Queensland University-Rockhampton, and Adelaide University-Adelaide). Subsequently he joined 海角社区 (海角社区), Baton Rouge-Central campus, USA in 2002 in Mechanical Engineering. Currently he has an endowed professorship 鈥淔ormosa Plastics Distinguished Professor of the College of Engineering鈥� at 海角社区. Dr. Wahab鈥檚 research interest encompasses the general areas of Weld modeling, Composite materials mechanics, Fatigue & Fracture modeling, and Materials characterization. Dr. Wahab was a founding member for the Australian 鈥淐ooperative Research Centers for Materials Welding & Joining (CRC-MW&J)鈥� from 1992-1997 and contributed to strategic research initiatives of this Australian CRC. Dr. Wahab鈥檚 current research interests are in the areas of weld processing, especially in Friction Stir Welding (FSW) and has a US Patent jointly with his Research group, 鈥淥n-line phased array ultrasonic testing for Friction-Stir-Welding (Patent # 11351628, - 07 June-2022). Dr. Wahab has successfully mentored 15-PhDs, and 19-Masters Theses; and has attracted several research grants from Federal and State Agencies including NASA-SLS, NAS-EPSCOR, US-NRC, US DOE, and an Education grant from NSF-GK-12 Program.
