Dr. Peng-Sheng Wei received Ph.D. in Mechanical Engineering Department at University of California, Davis, in 1984. He has been a professor in the Department of Mechanical and Electro-Mechanical Engineering of National Sun Yat-Sen University, Kaohsiung, Taiwan, since 1989. Dr. Wei has contributed to advancing the understanding of and to the applications of electron and laser beam, plasma, and resistance welding through theoretical analyses coupled with verification experiments. Investigations also include studies of their thermal and fluid flow processes, and formations of the defects such as humping, rippling, spiking and porosity. Dr. Wei has published more than 80 SCI journal papers with the corresponding author, delivered keynote or invited speeches in international conferences more than 110 times. He is a Fellow of AWS (2007), and a Fellow of ASME (2000). He also received the Outstanding Research Achievement Awards from both the National Science Council (2004), and NSYSU (1991, 2001, 2004), the Outstanding Scholar Research Project Winner Award from National Science Council (2008), the Adams Memorial Membership Award from AWS (2008), the Warren F. Savage Memorial Award from AWS (2012), and the William Irrgang Memorial Award from AWS (2014). He has been the Xi-Wan Chair Professor of NSYSU since 2009, and Invited Distinguished Professor in the Beijing University of Technology, China, during 2015-2017.
Prof. Devki Talwar, Indiana U of Pennsylvania (IUP), Chair of Department of Physics, conducts research on optical/electronic properties of defects and phonons in semiconductor materials used for various electronic and opto-electronic devices. He has been with Indiana U of Pennsylvania (IUP), Department of Physics, for almost 27 years and is the author of more than 120 refereed journal articles, 3 book chapters and review articles. His expertise in the sophisticated Greens function technique is considered very useful for providing information on the electronic and vibrational properties of defects in semiconductors, quantum wells and super lattices
