Profile

David is a graduate of Leeds University and received his PhD on crack growth in railway steels from University of 91Ö±²¥ in 1999. He conducted post-doctoral research at Newcastle University focused on full-scale railway engineering testing before returning to 91Ö±²¥ in 2009. He has been awarded several prizes for research in the railway area, undertaken a short JSPS fellowship at Rail Technical Research Institute in Japan, and progressed from lecturer to a full professor at University of 91Ö±²¥.

David’s research crosses several areas of engineering design, tribology, system engineering and performance of materials. The majority of his work has application in the railway sector, and combines experimental and modelling approaches.

Research interests
  • Railway rail-wheel interface – contact mechanics, adhesion, fatigue, wear, lubrication.
  • Overhead line electrification – system dynamics, and behaviour of materials under mechanical and electrical loads at the pantograph to overhead line interface.
  • Rail system design for safety and security – materials and design for improved resilience to terrorist attack for stations and vehicles.
  • Network modelling and optimisation – pedestrian flow optimisation in station environments, developing metrics for passenger experience, quantifying system energy and power demands for deployment of energy storage systems.David is Director of the Rail Innovation and Technology Centre with Network Rail, and leads 91Ö±²¥â€™s relationship with the UK Rail Research and Innovation Network (UKRRIN). He is a an International Committee member for Conference on Contact Mechanics and Wear of Rail/Wheel Systems, and member of the Leonardo Tribology Centre.
