New Zealand’s First IMO Gold Medallist (2002)Associate Professor In Number Theory, University Of MelbournePhD Princeton 2010 Under Peter SarnakResearches Subconvexity Of L-functions And Eigenfunction Concentration On Arithmetic Manifolds

Simon Marshall is an Associate Professor of Mathematics (Number Theory) at the University of Melbourne. He was previously on the faculty at the University of Wisconsin-Madison (2014-2025), and earned his PhD at Princeton University under Peter Sarnak. His research spans automorphic forms, representation theory and harmonic analysis, with a focus on subconvexity for L-functions, the limit multiplicity problem, and the concentration of eigenfunctions on arithmetic manifolds. As a school student in New Zealand he won a silver medal at the 2001 International Mathematical Olympiad and New Zealand’s first gold medal at the 2002 IMO.

Simon Marshall is an Associate Professor in Number Theory at the University of Melbourne. He spent 2014-2025 on the faculty of the University of Wisconsin-Madison and earned his PhD at Princeton University in 2010 under Peter Sarnak, with a dissertation titled 'On the Cohomology and Quantum Chaos of GL_2'. His research spans automorphic forms, representation theory and harmonic analysis, focusing on subconvexity bounds for L-functions, the limit multiplicity problem, and how eigenfunctions concentrate on arithmetic manifolds. Before his academic career he was a standout school mathematician in New Zealand: silver medallist at the 2001 IMO and gold medallist at the 2002 IMO, New Zealand's first.
