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.

Teaching

  • EG-184 Mechanical Properties of Materials

    The course provides a basic understanding of the relationship between the microstructure and the mechanical properties of metals. It will build on certain aspects of mechanical performance introduced in MT101 (Introduction to Materials Engineering) and provide a reference point for supplementary modules in Years 2 and 3.

  • EG-188 Engineering Analysis for Materials 2

    To provide additional grounding in engineering analysis methods for materials students. The module will cover the most important analytical tools and methods used in engineering and will relate these to common materials-related examples. The module will ensure the required grounding in methods and techniques for those who have not previously covered this area, or who are retuning after a gap. It will also provide opportunities for extension to more complicated examples for those who have more prior experience.

  • EG-213 Mechanical Properties of Materials

    The course provides a basic understanding of the relationship between the microstructure and the mechanical properties of metals. It will build on certain aspects of mechanical performance introduced in EG-180 (Introduction to Materials Engineering) and provide a reference point for supplementary modules in later years of the study. Module Aims: to introduce the underlying principles of the mechanical properties of engineering materials
