Introduction

Professor Ian Sloan was born in Melbourne to a family of scholars, teachers, and sports people. He completed a degree in undergraduate physics and mathematics at the University of Melbourne, a master’s degree in mathematical physics at the University of Adelaide, and a PhD in theoretical atomic physics at the University of London.  

In this interview, Professor Sloan recalls his childhood influences, what sparked his interest in science, studies, and his early career with the Colonial Sugar Refining Company (CSR), which supported him through his PhD in England. He returned to Australia and joined the University of New South Wales as a lecturer in 1965. He has been there ever since, as Personal Chair of Mathematics (1983), Head of the School of Mathematics (1986 – 1990, 1992 – 1993) and now as Emeritus and part-time Professor in the School of Mathematics and Statistics.

Professor Sloan talks here of his challenging transition from theoretical physics into computational mathematics and numerical analysis, the difference between how physicists and mathematicians operate, and the profound impact of the computer revolution on his work. He recalls the development of his department at UNSW and fostering of Australia’s premier numerical analysis program, whose students have gone on to have a significant impact in both industry and academia.

Professor Sloan remains active in the research community and offers insight into how he works, what makes a difference and how he feels about the future of science and mathematics in Australia.
