Graeme Bryce Segal FRS is an Australian mathematician, and professor at the University of Oxford.

Biography

Segal was educated at the University of Sydney, where he received his BSc degree in 1961. He went on to receive his D.Phil. in 1967 from St Catherine's College, Oxford; his thesis, written under the supervision of Michael Atiyah, was titled Equivariant K-theory.
His thesis was in the area of equivariant K-theory. The Atiyah–Segal completion theorem in that subject was a major motivation for the Segal conjecture, which he formulated. He has made many other contributions to homotopy theory in the past four decades, including an approach to infinite loop spaces. He was also a pioneer of elliptic cohomology, which is related to his interest in topological [quantum field theory].
Segal was an Invited Speaker at the ICM in 1970 in Nice and in 1990 in Kyoto. He taught at Oxford University from 1964 to 1990, then became the Lowndean Professor of Astronomy and Geometry at the University of Cambridge from 1990 to 1999, and then a Senior Research Fellow of All Souls College, Oxford from 1999 to 2009. He was elected the President of the London Mathematical Society in 2011.
He was elected a Fellow of the Royal Society in 1982 and was awarded the Sylvester Medal by the Royal Society in 2010.
He is married to writer Marina Warner. They live in London.
