Born on October 21, 1961, in Yeongam County, Jeollanam-do, Lee attended Seho-buk Elementary School (now Jangcheon Elementary) and graduated from Yeongam Seho Middle School. He then studied chemical engineering at Hanyang University and earned a master’s degree in chemical engineering from Hanyang’s Graduate School of Industrial Studies in 1993.
