He is also Vice-President of the International Union of Crystallography. His PhD research between 1965 and 1968 was under the supervision of Kathleen Lonsdale at University College London, UK, working on the crystallography of organic mixed crystals. In 1968-1969 he was a Fellow at Harvard University, USA, and then from 1969 to 1976he was at the Cavendish Laboratory, Cambridge, UK. 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 ofcrystals 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.
