Lee Kwang-hee
Lee Kwang-hee is a South Korean physicist. Since 2007, he has served as the Director of the Research Institute for Solar and Sustainable Energies at Gwangju Institute of Science and Technology.Education
Lee is currently a Full Professor of Materials Science & Engineering Department and a Vice-Director of Heeger Center for Advanced Materials at the Gwangju Institute of Science and Technology, Korea. His major areas of interest include polymer devices such as polymer LEDs, polymer solar cells, and polymer FETs using semiconducting and metallic polymers. He received BS degree from Seoul National University in 1983, and MS degree from KAIST in 1985. Then he worked at the Korea Atomic Energy Research Institute as a Staff Researcher for 1985–1990. He moved to the USA for his doctorate study in 1990 at the University of California, Santa Barbara and obtained his Ph.D. degree in March 1995 under the supervision of Professor Alan J. Heeger. After finishing his post-doctoral work at UCSB during 1995–11997, he started his professorship at the Pusan National University in South Korea in 1997. In 2007, he moved to his current position as a Distinguished Professor of GIST.Outstanding breakthroughs
