Martin Wechselberger

Martin Wechselberger is Professor in the School of Mathematics and Statistics at the University of Sydney, a position he has held since January 2015. He progressed through the academic ranks at the same institution: Associate Professor from January 2012 to December 2014, Senior Lecturer from January 2008 to December 2011, and Lecturer prior to that, having joined the University of Sydney in 2006. Before his appointment in Australia, Wechselberger completed a three-year postdoctoral position in the United States and held a Postdoctoral Research Fellowship in the Department of Applied Mathematics at Vienna University of Technology. His academic qualifications include a PhD in Mathematics from the Department of Applied Mathematics, Vienna University of Technology, awarded in October 1998 under the supervision of Professor Peter Szmolyan, and an MSc in Mathematics from the same department in January 1996, also supervised by Szmolyan. Wechselberger's research specializes in dynamical systems and ergodic theory, with applications to mathematical biology. He is actively involved in the Applied Mathematics Research Group and the Sydney Dynamics Group at the University of Sydney. His work aligns with the Faculty of Science research strengths in Complex Systems, Brain Behaviour and Cognition, and Fundamental Laws of Nature.

Wechselberger has made significant contributions to geometric singular perturbation theory and multi-timescale dynamical systems, earning the J.D. Crawford Prize from the Society for Industrial and Applied Mathematics (SIAM) in 2017 for achievements in this area. He authored the monograph Geometric Singular Perturbation Theory Beyond the Standard Form, published by Springer in 2020. As chief investigator, he has secured multiple Australian Research Council Discovery Project grants, including $467,099 for project DP220101817, $432,000 in 2022 for "A coordinate-independent theory for multi-time-scale dynamical systems," and $660,464 in 2025 for developing new mathematical tools to predict sudden changes in ecosystems. His publication record includes numerous papers in leading journals such as SIAM Journal on Applied Dynamical Systems and Quarterly of Applied Mathematics, with a notable 2005 paper in the former garnering over 330 citations. Wechselberger has supervised several doctoral students at the University of Sydney, including Samuel Jelbart (2020), Kerry-Lyn Roberts (2017), and John Mitry (2016).
