Chair in Mechatronics


Peter (Weiliang) Xu joined the University of Auckland on 1  February 2011, as Chair in Mechatronics Engineering.  He was the Professor of Mechatronics (2007-2010), Associate Professor (2005-2006) and Senior Lecturer (1999-2004) in School of Engineering and Advanced Technology, Massey University, New Zealand. Prior to coming to New Zealand, he worked at the City University of Hong Kong (1993-1998), the University of Stuttgart, Germany (1990-1992) and Southeast University, China (1988-1989).

His current research interests are mainly in areas of advanced mechatronics/robotics with applications in medicine and foods. He is Senior Member of IEEE and Fellow of Engineering New Zealand. He is Associate Editor for IEEE Transactions on Industrial Electronics and ASME Journal of Science and Engineering in Medical Diagnostics and Therapy.

Professor Xu is the Principal Invstigator for Research Theme "Intervential Technologies" and the Leader for Platform Technology "Actuation and Control" at the New Zealand Medical Technologies Centre of Research Excellence (CoRE).

Professor Xu is also an Associate Investigator at Riddet Institute, The New Zealand Centre of Research Excellence (CoRE) in Food, Innovation and Health and The Dodd-Walls Centre for Photonics and Quantum Technologies, The New Zealand Centre of Research Excellence (CoRE).

Professor Xu is the Speaker of Joint Graduate School on Soft Tissue Robotics between universities of Auckland, New Zealand and Stuttgart, Germany, an IRTG (International Research Training Groip) programme funded by DFG (German Science Foundation), since 2017.

During his 2017 sabbatical leave, Professor Xu was Guest Professor at the University of Stuttgart, Germany, working on a funded project Soft Tissue Robotics, with Institute of Control Technologies for Machine Tools and Manufacturing Units (
