Mark Wenman began work as the EDF Energy Research Fellow in Nuclear Fuels at Imperial College London at the beginning of Nov 2008. He obtained a degree in Materials Science and Technology (BEng) from the University of Birmingham between 1996-1999 and stayed at Birmingham University to carry out a PhD on the micromechanisms of fracture in the ductile-to-brittle transition region of BCC alloys. Having completed his PhD, in 2003, Mark was appointed as a Lecturer in the Reactor Engineering Group at the Nuclear Department, HMS Sultan in Gosport.

Mark has teaching experience in general nuclear engineering and has taught Reactor Dynamics and Materials Science at MSc level.  He set-up the MSc in Nuclear Engineering at Imperial College in 2010 and was course director for 3 years.  Mark has been involved in several external committees as an independent expert.  These include the Technical Advisory Group for Structural Integrity (TAGSI), Core Materials Working Group (Rolls-Royce/MoD) and is also  UK academic representative for the Fuels Working Group and UK Governance Board for the European Jules Horowitz reactor project.

His key research interests are in the field of nuclear engineering materials (specialising in metallurgy) and include micromechanisms of fracture, hydrogen embrittlement and corrosion, irradiation damage and modelling from continuum through to micro and atomic scales. Materials include zirconium alloys, stainless steels and ferritic steels.
