After attending a state grammar school and 6th form college in Manchester, I studied metallurgy, economics and management at St Anne’s College, Oxford. I stayed on at St Anne’s to do a DPhil in materials. I then spent several years in the Materials Department in Oxford working first as a postdoctoral researcher, then as a departmental lecturer, including having teaching responsibilities at Pembroke College and a Junior Research Fellowship at Linacre College. In 2000, I was appointed to a lectureship in Oxford and a Fellowship at Queen’s.


I tutor the first and second year material scientists at Queen’s, Corpus Christi and Mansfield colleges in aspects of phase transformations, microstructures and processing of materials. I also teach part of a third year options course in advanced manufacturing of metals and alloys. I supervise Part II (fourth year) materials undergraduates during their final year projects and graduate (DPhil) students.


In my research I study solidification processing of advanced materials from laboratory scale through to pilot-scale processing plant. I have particular interests in controlling the grain structure of the metal, controlling the phases which form in the materials and in maintaining quality whilst re-cycling metals. My main focus is on working with aluminium alloys and intermetallics.
