Prof. Yong-Hee Lee is the President of the Korea Institute for Advanced Study. He joined the Agency for Defence Development in 1979 and AT&T Bell Laboratories in 1987. In 1991, he joined the Department of Physics in KAIST. During his stay at AT&T Bell Laboratories, Prof. Lee pioneered and demonstrated the 850-nm proton-implanted top-emitting VCSELs in 1990 and holds the original patent on this industrially-accepted VCSEL. In 1991, he joined KAIST and has continued his researches on VCSELs. Recently his main interest lies on photonic nano-structures and nano-photonic integrated circuits. His laboratory demonstrated various forms of photonic crystal lasers. Within Korea, he has received the National Academy of Sciences Award (Natural Science) in 2002, the Science Prize (Physics) in 2010 from MOEST, and Korea Best Scientist Prize in 2015. He has co-authored over 180 papers related to nanophotonics, with cumulative citations of >12,000 and H-index of 56(Google Scholar). He advised and produced over 40 PhD students in physics during his stay at KAIST.
