Ph.D. (University of Toronto)

Professor Li Qiu received the Ph.D. degree in electrical engineering from the University of Toronto in 1990. After briefly working in the Canadian Space Agency, the Fields Institute for Research in Mathematical Sciences (Waterloo), and the Institute of Mathematics and its Applications (Minneapolis), he joined the Hong Kong University of Science and Technology, Hong Kong SAR, China in 1993 and is now an Emeritus Professor in the Department of Electronic and Computer Engineering. In 2023, he took a leave to work in Southern University of Science and Technology, as a Chair Professor. He joined The Chinese University of Hong Kong, Shenzhen in 2024, as a Presidential Chair Professor. Prof. Qiu's research interests include system, control, optimization theory, and mathematics for information technology, as well as their applications in manufacturing industry and energy systems. He is also interested in control education and co-authored an undergraduate textbook "Introduction to Feedback Control" which was published by Prentice-Hall in 2009. He served as an Associate Editor of the IEEE Transactions on Automatic Control and Automatica. He was the General Chair of the 7th Asian Control Conference, which was held in Hong Kong, China in 2009. He was a Distinguished Lecturer from 2007 to 2010 and was a Member of the Board of Governors in 2012 and 2017 of the IEEE Control Systems Society. He was a Vice President of the Asian Control Association and the Founding Chairperson of the Hong Kong Automatic Control Association. He is a Fellow of IEEE, a Fellow of IFAC, and an inaugural Fellow of ACA (Asian Control Association).
