Profile

Professor Roger Lewis became a lecturer in the Department in 2002 and was promoted to Senior Lecturer in 2006, before becoming a Reader in 2011 and then being awarded a personal chair in 2013.

He graduated from The University of Sheffield in 1996 with an MEng in Mechanical Engineering and continued to work at Sheffield towards a PhD in the Tribology Research Group. He then had posts as a Research Associate and Teaching Fellow in the Department.

In 2001 he was awarded the Tribology Trust Bronze Medal and in 2003 received a Brian Mercer Award for Innovation from the Royal Society. He also received the Institute of Physics Innovation in Tribology Prize in 2008. He was awarded the Donald Julius Groen Prize in Tribology in 2020. He is a Chartered Engineer and Fellow of the IMechE.

In 2019 Roger was made a Royal Academy of Engineering Research Chair. This position is co-funded by the Rail Safety and Standards Board and will focus on management of low adhesion in the wheel/rail interface.

Roger has edited an essential guide to wheel/rail contacts issues, 'The Wheel/Rail Interface Handbook' which is published by Woodhead.

Roger is a member of the Leonardo Tribology Centre.

Research interests

Roger's research interests are split into three areas: solving industrial wear problems; application and development of a novel ultrasonic technique for machine element contact analysis and design of engineering components and machines. The research themes are wide ranging, but the main focus is on:

Railway Engineering

Wheel/rail contact tribology – including wear (wheel profile evolution), RCF, friction management (use of top of rail friction modifiers; grease lubrication and traction gels), isolation and links to effective train detection
Rail infrastructure improvement – including laser cladding of rail to reduce wear/RCF; design and testing of insulated rail joints; overhead line wear testing
Condition monitoring – including real-time measurement of the wheel/rail contact; force measurement and detection of loosening in bolted joints.

Human Interactions

Fundamental characterization and modelling of skin friction including use of OCT to determine sub-surface skin strain
Hand/object interactions – including kitchen equipment, sports equipment etc. and effects that wearing medical examination gloves has on dexterity, grip and tactile discrimination
Human tissue interaction with medical devices including catheters
Pedestrian slips and falls, particularly barefoot slips and characterisation of flooring performance
Multi-scale modelling of skin to incorporate effects of moisture and temperature to optimise design of medical products that interface with skin.

Teaching activities

Professor Lewis has most recently taught tribology and sustainable design to fourth years. He led the development of a ground breaking interdisciplinary sustainable design project based on local live development sites.

This involves Civil and Structural Engineering, Architecture, Town and Regional Planning and Landscape. Professor Lewis has won three University of Sheffield Senate Teaching Awards for his innovation in teaching methods.
