Background
Mark completed his undergraduate degree in Automotive Materials at the Department of Materials (formerly IPTME), Loughborough University. He then went on to study for a PhD in oxidation of stainless steels with Rebecca Higginson which he received in 2008 (thesis here: http://hdl.handle.net/2134/4435 ).
After his PhD he worked as a research associate at Materials Science and Engineering (then Department of Engineering Materials) at the University of Sheffield studying secondary electron dopant contrast. Currently, Mark is a research associate at the Department of Materials working with Professor Rachel Thomson on steels and superalloys for power plant applications.
