Profile

Professor Tom Slatter graduated from the University of Sheffield in 2004 with an MEng in Mechanical Engineering and in 2010 with a PhD in Mechanical Engineering. During this time he worked for the Ford Motor Company in powertrain CAE and diesel engine engineering.

His PhD was sponsored by the Ford Advanced Research and Materials Group in Aachen, Germany and concerned the wear of automotive valvetrain components.

In 2007, Tom became a University Teaching Associate, was appointed Lecturer in Mechanical Engineering in 2011, promoted to Senior Lecturer in 2018 and to a Personal Chair in 2022. Tom is a member of the Leonardo Tribology Centre and is a Co-Director of the EPSRC Centre for Doctoral Training in Integrated Tribology (iT-CDT).

Research interests

Professor Slatter continues to be involved in automotive tribology research; continuing work on valvetrain wear with a number of automotive OEMs, investigating the wear of other powertrain components (eg. chains, crankshafts), the damage caused by sooty oil, the life of engine lubricants and assessing the performance of environmentally acceptable lubricants.

Recent research and consultancy work in these areas has included projects with companies such as Jaguar Land Rover, Caterpillar, Jacobs Vehicle Systems, and several F1 teams.

Tom's research interests also include tribology in manufacturing with projects investigating the design, performance and instrumentation of manufacturing machines, processes and tooling with organisations such as Sandvik Coromant, Collins Aerospace, Rolls-Royce, Kennametal, the University’s two HVM Catapults (Advanced Manufacturing Research Centre (AMRC) and Nuclear Advanced Manufacturing Research Centre (NAMRC)), and a number of specialist engineering SMEs.

Outside of these applied areas, Tom works at a more fundamental level investigating topics including: friction, the role of surfaces in contact transmission, impact wear and the cryogenic treatment of metals (with Dr Rob Thornton, University of Leicester
