He was educated at Highgate School, King's College London (BSc Mathematics and Physics, 1967) and the University of East Anglia (PhD, 1971).[2] He was appointed a Fellow in Mathematics at Jesus College, Oxford in 1977 and became an Emeritus Fellow in 2008. He served at President of the Mathematical Association from 2010 to 2011. He was awarded an Honorary Doctorate of Science from the University of East Anglia in 2013.[3]

His early research was on geophysical and astrophysical fluid dynamics, beginning with the discovery in 1972 of a magnetic 'field gradient' instability in rotating fluids.[4] In 1976, he discovered the first examples of wave over-reflection (i.e. reflection coefficient greater than unity) in a stable system. In 1978 his research focused on magnetic fields and differential rotation in stars, with new results on magnetic buoyancy, the Taylor instability, Goldreich-Schubert instability, and, 'magnetorotational' instability. In 1992 he discovered the 'upside-down pendulums theorem' (which is very loosely connected with the Indian Rope Trick).
