The 2024 ANZIAM Medal is awarded to Professor Hinke Osinga of the University of Auckland.

Professor Hinke Osinga is an internationally renowned researcher in the analysis, characterisation and computation of invariant manifolds of chaotic dynamical systems. Her scientific publications, numbering well above 100, have over 3800 citations recorded on ResearchGate.

Her methods are uniquely supported both by robust convergence proofs and by open source software enabling them to be used by research groups worldwide. Professor Osinga’s research includes the development and investigation of the geometric ingredients of a new type of high-dimensional chaos, called wild chaos. She has pioneered new methods for demonstrating the existence of wild chaos and for visualising and understanding how it is created or destroyed. Professor Osinga’s remarkable achievements have been recognised worldwide, by an array of awards and fellowships. This includes: being elected Fellow of SIAM, the largest applied mathematics society in the world; the Research Award of the New Zealand Mathematical Society; the London Mathematical Society/New Zealand Mathematical Society Aitken Lectureship; and the Moyal Medal, awarded annually by Macquarie University. Professor Osinga was the first female mathematician to be made a Fellow of the Royal Society of New Zealand.

She has a total of over $6M of income on individual grants, as well as being a principal investigator for the Dodd-Walls Centre of Research Excellence. 20 past and present PhD students have benefited from her supervision.

Professor Osinga is a natural leader within our community, and is currently chair of the New Zealand branch of ANZIAM. She has previously served on the Executive Committee, is a member of the editorial board of the ANZIAM journal, was on the scientific committee for the 2020 ANZIAM meeting, and has chaired or been a member of many prize committees within the Australia-New Zealand mathematics community. She has organised Women in Science events in Auckland, spoken at events for undergraduates, and is a mentor for many junior female mathematicians.

She has been an associate editor on nine applied mathematics journals, including some of the top journals in the field. She was involved with founding the online magazine DSWeb, and has been involved with committee work for international organisations such as SIAM and the International Congress of Mathematicians.

Her beautiful crocheted version of the Lorenz manifold has drawn substantial international media attention around the world since 2004: she appeared on Channel 4 News in the UK, Channel One TV News in Russia and CBC Radio in Canada, as well as in numerous print media outlets in the USA, UK, Germany, The Netherlands and Australia. Despite these many aspects of her work achievements, Professor Osinga freely gives of her time to speak not only in scientific conferences but also in many community and school education engagements.
