Profile: I am a Lecturer in the Manufacturing & Structural Integrity group, within Mechanical Engineering. I grew up in York and my undergraduate degree was in Natural Sciences at Selwyn College, Cambridge. I started my career as a Manufacturing Engineer at Rolls-Royce in Derby, working on single crystal casting of turbine blades for gas turbine engines, specifically on non-contact measurement and yield improvement using FE modelling. I moved to Sheffield to do a PhD in additive manufacturing of magnetically graded stainless steels, for which I was awarded the Bruton Medal from the University of Sheffield, and the EPMA Doctoral Thesis prize.

I produce new types of materials which can respond to their environment by changing their mechanical behaviour.
