Weimin Yang was born in Hunan, China, in 1965. He received the B.S., M.S., and Ph.D. degrees in mechanical engineering and automation from the Beijing University of Chemical Technology (BUCT), Beijing, China, in 1998. From 1990 to 1992, he was Research Assistant. From 1992 to 1995, he was Lecturer. From 1995 to 1999, he was Associate Professor. Since 1999, he has been Changjiang Distinguished Professor with the Institute of Mechanical and Electrical Engineering, BUCT. He held Postdoctoral Research position with the University of Tokyo (U-Tokyo), Tokyo, Japan, in 2002. He is Author of eight books and more than 300 articles. He holds over 106 inventions (authorized). His research interests include advanced manufacturing technology (AMT), computer-aided design/engineering/manufacturing (CAD/CAE/CAM), multidisciplinary design optimization (MDO), functional material molding, and control engineering. Dr. Yang received the awards and honors which include the Top Award of Chinese CAE AnnualMeeting, the National Science and Technology Progress Award, and the Provincial Science and Technology Award. Ranran Jian was born in Shandong, China, in 1991. He studied the B.S., M.S., and Ph.D. degrees in mechanical engineering and automation from the Beijing University of Chemical Technology (BUCT), Beijing, China, in 2010-2019. From 2018 to 2019, he was visiting scholar at the University of Toronto (U of T), Toronto, Canada. Since 2020, he has been Associate Professor with the College of Electromechanical Engineering at the Qingdao University of Science and Technology(QUST), Qingdao, China.Dr. Jian is Author of more than 50 peer-reviewed papers and co-authored 3 books. He holds over 20 inventions (authorized). He specializes in polymer processing and advanced manufacturing technology (AMT), whose research combines advanced manufacturing with novel technologies and approaches, heat and mass transfer enhancement and thermal management, 3D printing and 3D copying technology, functional biocarbon composites and lightweight products. Dr. Jian is a screw expert and a fellow of the Society of Plastics Engineers (SPE), USA. He is hugely interested in translating research into commercialization and works with many companies worldwide.
