Professor Lang received his BS and MSc degree in the subject area of Automatic Control in China, and PhD degree in the Department of Automatic Control and Systems Engineering at the University of Sheffield, UK. After several years' postdoctoral positions at Sheffield, he became a Lecturer in Automatic Control and Systems Engineering in 2003, was promoted to Senior Lecturer and Reader in 2008 and 2010, respectively, and has held the position of Chair in Complex Systems Analysis and Design in the Department of Automatic Control and Systems Engineering at Sheffield since 2013.

His main expertises relate to the theories and methods for complex systems modelling, analysis, design, and signal processing, and the application of these to resolving various engineering and scientific problems. The application areas include smart structures and systems, civil and mechanical structure vibration control, structural health monitoring, condition monitoring and fault diagnosis for wind turbine components and systems, optimal periodic operation of chemical reactors, digital manufacturing, and medical diagnosis.

Research interests
