He has served for many years as editor of the preeminent journals, notably Annals of mathematics. His honours include the Wolf Prize in Mathematics (2014) and the Sylvester Medal (2019). He is a Fellow of the (UK) Royal Society and a Member of the (US) National Academy of Sciences, and he has also worked to develop the mathematical sciences in his native South Africa."
