SUMMARY

This IGA workshop, marking Keith Hannabuss's 60th birthday, is in honour of his key contributions to mathematical physics. Keith completed his DPhil on quantum theory in de Sitter spacetime in 1969 with John Lewis as his supervisor at Oxford. He then had a junior research fellowship at Magdalen College (Oxford) and also spent a year as a Moore Instructor at MIT.  Keith commenced his permanent appointment at Balliol College (Oxford) in 1972, and his first DPhil student was Alan Carey. This started Keith's long association with Australia, where he has frequently visited and has had several collaborators, especially at the University of Adelaide, collaborating on integrable systems, quantum Hall effect and duality in string theory.
