Professor Ling Wang is Professor of Tribo-Sensing within Engineering and Physical Sciences at the University of Southampton.

Combining tribology with sensing technologies provides intelligence and produces smarter engineering systems

Ling is Professor of Tribo-Sensing at the national Centre for Advanced Tribology at Southampton (nCATS) within Mechanical Engineering Department in the Faculty of Engineering and the Environment. She has over 20 years research experience in the field of tribology and sensing. She chairs the University Strategic Research Group (USRG) on Monitoring of Engineered and Natural Systems Using Sensors (MENSUS) and is the deputy head of National Centre of Advanced Tribology Centre at Southampton (nCATS).

Ling has published over 100 peer reviewed papers and led a number of collaborate research projects sponsored by EU, UK Research Councils and a range of industrial partners including Rolls-Royce plc., GE Aviation, Vestas Wind Systems, Shell Global Solutions, Afton Chemical Corporation, John Crane and Schaeffler Group, with an over £8M grant portfolio.  

Career History

Ling obtained both her BSc and MSc in Chemistry from Nankai University in China, and her Diploma in Environmental Engineering from Portsmouth University and PhD in Systems Engineering from Southampton Solent University in the UK. She joined the Tribology and Surface Engineering Group at University of Southampton since 2001.

Structured Surfaces for Tribological Applications

Using structured surface rather than smooth surface to decrease friction is at variance with the classical tribology theories. However, it really happened and has been proved by worldwide researchers.
