My research focuses on a range of topics around advanced materials for aerospace and power generation.

My most significant research challenges have involved the development of a unique test facility for the mechanical characterization of alloy systems in hot gas atmospheres, including sulphur dioxide. Spotting a ‘gap in the market’ and being both a new and enthusiastic academic, I jumped at the chance to prove myself, later realizing I may have been a little rash! However, 4 years down the line, I now have a facility that is globally unique and successfully generating data and providing critical insight into advanced materials under extreme conditions. As already mentioned, research moves on: so now the questions are ‘can we go hotter?’, ‘can we incorporate water vapour?’, ‘what about superheated steam?’.

All of these have their own challenges - that is what being an academic is all about.
