Professor Pwt Evans leads the tribology and contact mechanics research group at the Cardiff School of Engineering. He received his higher education at the University of Exeter, from which he holds BSc, PhD and DSc degrees. He is a chartered engineer and a Fellow of both the Institution of Mechanical Engineers and the Learned Society of Wales; he was awarded the Tribology Trust Silver medal in 2009. He has researched in the field of elastohydrodynamic lubrication since his post-doctorate research, where he produced the first point contact EHL solutions at realistic engineering loads. He has worked on a range of projects with many companies - mainly in the EHL field - and has published some 150 technical papers in this area. His main interests are in mixed lubrication and micropitting in gears, but he also has interests in plain bearings and in self-lubricating, composite liner bearings.
