  • About the Laboratory & Research Area
  • NML(Nano/Micro Systems and Controls Laboratory) conducts research and development in MEMS (Micro Electro Mechanical Systems) and control technologies. Professor Cho started the MEMS research from its embryonic stage. He has served as an editor of IEEE/ASME Journal of MEMS since its first issue in 1992, and was appointed as a Senior Editor in 2012. In addition, he currently serves as the Vice-Chair of the Technical Board of IFAC (International Federation of Automatic Control). The laboratory is comprised of 9 Ph. D. and 5 M.S. candidates and focuses on the research of MEMS and control technologies. Professor Cho publishes extensively in leading journals and also has more than one hundred patents and patent applications. He also transferred many patents to companies.
