Brief Introduction of Professor CHEN Guanrong

Professor Guanrong Chen is a Member of the European Academy of Sciences, a Member of the European Academy of Engineering, and fellow of the World Academy of Sciences. He currently serves as Chair Professor and Doctoral Supervisor in the Department of Electronic Engineering at the City University of Hong Kong. Professor Chen obtained his Master’s degree in Computational Mathematics from Sun Yat-sen University in Guangzhou in 1981 and his Ph.D. in Applied Mathematics from Texas A&M University, USA, in 1987. He subsequently taught at Rice University and the University of Houston in the United States. Since 2000, he has held the position of Chair Professor at the City University of Hong Kong. Professor Chen was elected as an IEEE Fellow in 1997. He received the Second Prize of the National Natural Science Award in 2008, 2012, and 2016, the Ho Leung Ho Lee Foundation Science and Technology Award in 2010, an honorary doctorate from Saint Petersburg State University in Russia and the Euler Gold Medal from the Euler Foundation of Russia in 2011, an honorary doctorate from the University of Normandy in France and election as a Member of the European Academy of Sciences in 2014, and election as a Member of the European Academy of Engineering and a fellow of the World Academy of Sciences in 2015.

Professor Chen has established and developed a rigorous yet practical theoretical framework for chaos anticontrol. He first proposed fundamental criteria and algorithms for feedback-induced chaos in discrete systems (known as the Chen-Lai system) and infinite-dimensional systems. He discovered the dual system of the Lorenz system (referred to as the "Chen system") and the critical chaotic systems between them. He introduced a single-parameter unified chaotic system, generalized Lorenz systems and their canonical forms, hyperbolic-type generalized Lorenz systems and their canonical forms, and established the theoretical framework for the entire family of generalized Lorenz systems. Collaborating with peers, he proved the robustness of scale-free networks against random attacks and their vulnerability to targeted attacks, proposed novel ideas and algorithms for pinning control of complex networks, applied mathematical graph theory to characterize the synchronization capability and synchronization regions of complex networks with analytical results, and developed the Local Area Network (LAN) and Multi-LAN models for the internet.
