Dr. Kwang-Ryeol Lee is now a principal research scientist in the center for computational science and director-general of the Institute for Multidisciplinary Convergence of Matter at Korea Institute of Science and Technology (KIST). After receiving Ph.D degree in 1988 at KAIST, he joined Division of Applied Science at Harvard University to study kinetics of the laser annealing of semiconductor surface. In 1991, he joined KIST and has been studying both fundamental aspects and industrial application of the DLC coating technology. He published about 180 SCI journal papers and 45 patents. He succeeded in the technology transfer to industry of DLC coating technology to VCR head drum, IC forming and trimming die, dental and micro-drill, and various sliding tools. For 2002 - 2010, he served as a Session and Symposium Chair of the Carbon and Nitride Coating Symposium in the International Conference of Metallurgical Coating and Thin Films (ICMCTF), one of the American Vacuum Society Conference. He received 4 times the Best Research Award of KIST and the Commendation of the Prime Minister of Korea in 2005. From 2001, his research was extended to the computational nano-science to understand atomistic or sub-atomistic behavior of materials, thin films and nanostructured surface evolution. He has organized number of international symposium on computational materials science. His recent project is to develope web-based computational research platform to design nano-devices and energy materials.
