Ray Snidle is a (semi-retired) professor of mechanical engineering at Cardiff University where he contributes to the tribology and contact mechanics research group. A chartered engineer and Fellow of both IMechE and ASME, he holds PhD and DSc degrees from Leicester University prior to his obtained industrial experience at Rolls-Royce Aircraft Engines, Bristol. His dominant research interests are in the field of the tribology of gear tooth contacts, with particular emphasis on the failure of elastohydrodynamic lubrication (EHL) leading to scuffing and micropitting.
