B.S., M.S., Ph.D. Seoul National University, Korea

Prof. Lee received his BS (1983), MS (1985) and Ph. D (1992) degree from Seoul National University in Korea and conducted his post-doc. research at the Dept. of Structural Engineering, Univ. of Calif., San Diego, USA, during 1995-1996 and participated in the FEMA-funded steel SAC joint project. He joined SNU after teaching at Kyungnam University during 1988-2002. He teaches mechanics of materials, design of steel structures, structural stability and structural dynamics.

He has been the POSCO-affiliated research professor in architecture since 2007. He served as the president of Korea Society of Earthquake Engineering, the vise-president of Korea Society of Steel Construction. He also served as the national delegate of International Association of Earthquake Engineering and the coordinator for international seminar on seismic design of building structures among Japan, Taiwan and Korea. He was the representative writer of steel design specifications in 2016 Korean Building Code. He played a leading role in writing the first (2009 KBC) steel seismic provisions. He pioneered large-size cyclic seismic testing in Korea as early as mid 1990s and has been active in developing ductile seismic steel moment connections. He, as the director, led the innovative and rapid construction technology joint venture sponsored by the Korea government and construction industries for six years. He has been the recipient of more than10 honors and awards from Korean academic/professional societies such as National Academy of Engineering of Korea, Korea Society of Steel Construction, Korea Society of Earthquake Engineering, Korean Structural Engineers Association, and Korea Association of Steel and Iron. In 2019, he was selected as the member of IIW (international institute of welding) Sub-commission XV in recognition of his active research on high- strength steel tubular joints.

Over the past decade, he conducted more than 100 projects (about 70 projects as the principal investigator) from governmental/public sectors and private industries. His current research interests include structural system optimization using perimeter steel moment frame, high-strength steel tubular joints, high-strength steel bolted/welded joints, seismic design of nonstructural elements, and structural fire design.
