In 1976 he was appointed Lecturer in Physics at the Clarendon Laboratory Oxford and as an Official fellow and Tutor at Jesus College Oxford, UK. Glazer's research has mainly been in understanding the relationship between physical properties of crystals and their structures. He is perhaps best known for his classification system for tilted octahedra in perovskites. Patience Thomson is the daughter of William Lawrence Bragg and Alice Grace Jenny Bragg.
