Emeritus Professor Jon Berrick held positions in mathematics at Oxford and Imperial College London prior to joining the National University of Singapore (NUS) in 1981. In 2012, he became the inaugural Professor of Science (Mathematics) at Yale-NUS College, serving as Head of Studies for Mathematical, Computational and Statistical Sciences, and facilitator for the Quantitative Reasoning course in the Common Curriculum. In 2014/15, he was the first moderator for Full Faculty Meetings, and then chaired the Committee on Integrity and Discipline. Along with his several books and over 70 research papers in mathematics, he has had research collaborations in neurophysiology, anatomy, and public health and safety, especially tobacco control – a subject in which he has been lecturing at Yale-NUS. For work on the mathematics of braids, Professor Berrick received Singapore’s National Science Award in 2007. He has Honorary Professorships at University of Sydney and Western Sydney University, and is Editor-in-Chief of the Journal of the Australian Mathematical Society.
