个人简介

Leijun Li obtained his B.S. degree in welding engineering from Huazhong University of Science and Technology (Wuhan, China), and M.S. degree in mechanical engineering from Xian Jiaotong University (Xian, China). He was a faculty member from 1990 to 1994, first as a lecturer, and then as an associate professor, in the welding engineering program at Wuhan University. In 1994 he moved to United States for graduate studies in physical metallurgy. He obtained a Ph.D. degree in materials engineering from the Warren “Doc” Savage Materials Joining Lab at Rensselaer Polytechnic Institute (RPI). From 2000 to 2002, he served as a tenure-track assistant professor of manufacturing at the University of Northern Iowa (Cedar Falls, Iowa), where he taught physical metallurgy, welding, and metal casting. From 2002 to 2013, he served as a tenure-track and then tenured professor in the Department of Mechanical and Aerospace Engineering at Utah State University (Logan, Utah). Through funded research and graduate education in materials joining, his Materials Processing and Testing Lab has become a well-known research group of its kind in the United States. In 2013, he relocated from Utah to Alberta, and took up his present position at the University of Alberta. Leijun Li has been active with American Welding Society, serving on the Technical Papers and Testing of Welds committees, and as a Principal Reviewer for the Welding Journal. He chaired the Joining Critical Technologies committee of ASM International, besides serving as a Key Reader for the Metallurgical and Materials Transactions.
