Personal profile


Paul heads up the Bio-Metrology Research Group and is a key member and co-investigator in the EPSRC Future Metrology Hub with responsibility as research lead in the area of metrology for medical and biological applications. This remit bridges aspects of implant technology to characterisation of bio-active films and biological structures.

In January 2014 Paul took the role of Senior Lecturer in Automotive and Mechanical Engineering within the School of Computing Engineering and has performed various roles within the School serving as Director of Graduate Education, Deputy Director of Graduate Education, Deputy UoA Coordinator for Aeronautical, Mechanical, Chemical and Manufacturing Engineering, course leader for BEng/MEng Mechanical Engineering, course leader for BEng/MEng Energy Engineering and admissions tutor for the mechanical engineering subject area. His academic duties include teaching of Mechanical Science, Eco-Design & IPR and Dimensional Measurement Systems. Paul is also a key member of the EPSRC Centre for Innovative Manufacturing in Advanced Metrology.

Paul studied for a BEng in Mechanical Engineering at the University of Birmingham, graduating in 1999. He then moved on to complete an MSc in Engineering Design and Its Management at the University of Huddersfield, graduating in 2000.

As a direct result of his MSc work Paul went to work for DePuy International Ltd, a leading orthopaedics manufacturing company and part of the Johnson and Johnson group of companies. His work there led on to a PhD with the Surface Metrology Group at the Centre for Precision Technologies under the supervision of Prof Liam Blunt and Prof Jane Jiang with most of the project work completed at DePuy in Leeds and leading to graduation in 2008. Paul's PhD work involved the development of methods for the simulation and characterisation of wear in orthopaedic knee replacement joints.

In 2007 Paul was taken on as a Research Fellow at the Centre for Precision Technologies and then in 2011 as a Senior Research Fellow within the EPSRC Centre for Innovative Manufacturing in Advanced Metrology where he developed a reputation as a world renowned expert on the subject of orthopaedic wear measurement.
