Rob Dwyer-Joyce is Professor of Tribology and Lubrication Engineering in the Department of Mechanical Engineering. He is Director of the Centre for Doctoral Training in Integrated Tribology and manages the Leonardo Centre for Tribology.
He is a Fellow of the Royal Academy of Engineering and a Fellow if the Institution of Mechanical Engineers. He currently holds an EPSRC Advanced Career Fellowship in Tribo-Acoustic Sensors.
He has a first degree in Mechanical Engineering from Imperial College and a PhD in Tribology.
After graduating he worked for British Gas in the Petroleum Production Division and offshore on the Rough gas field. Rob joined the Department in 1994 and has taught fluid mechanics and tribology of machine elements to undergraduate and postgraduate students.
His research expertise is in industrial wear and lubrication problems, and the development of metrology tools for tribology.
His research team has developed a tribo-acoustic sensors that are used to measure oil film thickness, viscosity, and stress inside machine elements, and have been used in wind turbine bearings, marine diesel, and automotive applications.
- Research interests
-
Professor Dwyer-Joyce's research covers a range of industrial wear and lubrication problems. The work involves the development of metrology tools, experimental techniques (wear, friction, bearings and lubrication rigs), and advanced analytical models.
One research theme is the wear of engineering components. This involves testing on specimens and real components, as well as modelling and development of wear resistant systems. Projects have included wear of railway wheels, engine valves, wear of rolling bearings, polymer bearing and gears, aircraft landing gear pins, and drive chains.
Another activity is the development of sensors for studying interfaces in machine components.
Instruments have been developed to determine the contact area and pressure distribution. This has been used to study contacts in wind turbine bearings, nuclear reactor joints, automotive bearings and piston rings, marine diesel engines, and wheel/rail contacts.

- Teaching interests
-
Prof. Dwyer-Joyce has taught Fluids Engineering to Mechanical, Aerospace and Biomechanical Engineering students. This second year course is all about the interaction between fluids and engineering machines and structures. It gives students the tools to determine how the properties of liquids and gases are changed when they interact with components like pipelines, pumps, aerofoils or turbine blades, and how this results in transfer of force, torque, momentum and energy.
