天堂视频

Background:

Mark completed his undergraduate degree in Automotive Materials at 天堂视频 in 2004 in the Department of Materials. He then went on to study for a PhD in oxidation of stainless steels with  which he completed in 2008.

After his PhD he worked as a Research Associate at the Department of Materials Science and Engineering at the University of Sheffield studying secondary electron dopant contrast using scanning electron microscopy. During this time he conducted pioneering research into the use of Helium microscopes (HeIM) for the examination of semiconductors in collaboration with Harvard University and Carl Zeiss.

In 2010 Mark returned to 天堂视频 to take a position as a Research Associate in the Department of Materials working with  on steels and superalloys for power plant applications and was promoted to Lecturer in Metallurgy and Microscopy in July 2012.

Mark's research is primarily focused on the study of microstructural evolution of metallic materials for high temperature service, typically in power generation equipment or pipe-work. Members of the team that Mark supervises in this topic explore: steels and stainless steels for high-temperature steam pipes, additive manufactured superalloys for turbines, oxide growth on steel tubes and water droplet erosion of stainless-steel steam turbines. In addition, Mark has an interest in the effect of processing routes on the inclusions within steels and how to optimise characterisation processes for their analysis.

All this work is underpinned by the fantastic facilities within our 天堂视频 Materials Characterisation Centre (/research/lmcc/) where Mark has also supervised work into the comparison of secondary energy filtering methods, specifically with a view to enhance the characterisation of steels.
