Xingjian Jing received the B.S. degree from Zhejiang University, Hangzhou, China, in 1998, the M.S. degree from the Shenyang Institute of Automation, Chinese Academy of Sciences, Shenyang, China, in 2001, and the Ph.D. degree in nonlinear systems and signal processing from the Department of Automatic Control and Systems Engineering, University of Sheffield, Sheffield, U.K., in 2008. He is currently an Assistant Professor in the Department of Mechanical Engineering, Hong Kong Polytechnic University (PolyU), Hong Kong. Before joining PolyU, he was a Research Fellow with the Institute of Sound and Vibration Research, University of Southampton, Southampton, U.K., from August 2008 to November 2009, where he worked on biological signal processing in collaboration with neuroscientists and funded by the Biotechnology and Biological Sciences Research Council (U.K.). He has published more than 50 papers in refereed journals and conference proceedings. His current research interests include system identification, signal processing, control of complex nonlinear systems, nonlinear analysis in the frequency domain, intelligent computing methods and their applications in nonlinear mechanical systems (sound and vibration control), nonlinear physiological systems (neural systems), robotic systems, and others.
