My CV and my publication list are available to download as PDFs.

Video and slides of my lecture at the ICM in Rio.

Video of my Sydney Ideas lecture on "Math, AI and intuition"

Slides (and a video) from a colloquium in Berlin giving a historical introduction to representation theory.

My Takagi lectures (lecture one, lecture two) provide an introduction to some of the themes of my current research (for mathematicians).

News:

Charlotte Chan, Thomas Lam and I will organize a special semester on "Modern Perspectives in Representation Theory" in First Semester 2025.

I received the 2024 Max-Planck Humboldt Research Award. As part of this award, the University of Bonn will be advertising 3 postdoctoral positions to work with myself, Catharina Stoppel and other researchers in Bonn and Sydney. Please let smri.admin@sydney.edu.au know if you would like to be added to a mailing list for news about these positions.

Mike Douglas, Fabian Ruehle, Mike Freedman and François Charton and I are organising a special semester on Mathematics and Machine Learning at CMSA Harvard in Fall 2023. Please refer to the CMSA website for further information.

In 2023 I was awarded an Australian Laureate Fellowship. As part of the fellowship, SMRI will be advertising several positions in 2024 and 2025. Please write to smri.admin@sydney.edu.au if you would like to be added to a mailing list to be informed about such positions, or keep an eye on mathjobs.

In Semester 2 2023, Georg Gottwald, Harini Desiraju and myself organised a seminar series "Mathematical challenges in AI".

In Semester 2 2023, Dragan Milicic and I taught a special semester on D-modules and their use in representation theory.

In Semester 1 2023, Chris Hone and I taught a course on modular representation theory.

I gave a Public Lecture as part of the International Congress of Mathematicians on 8 July 2022 for the London Mathematical Society. Seminar recording and quote attributions for the talk.

I lectured at a summer school on recent perspectives in Hodge theory in Pisa in September 2022.

I facilitated a course at the joint AMSI / MSRI winter school in June to July 2022. Watch the lectures on Kazhdan-Lusztig Polynomials: Representation, Geometry and Combinatorics.

In Semester 1 2022, Georg Gottwald, Joel Gibson and myself organised a seminar on "Machine learning for the working mathematician".

If you are in Sydney, (or would like to pretend you are, and have an internet connection...) come to our informal Friday seminar!

Daniel Juteau, Simon Riche, Wolfgang Soergel organised an Arbeitsgemeinschaft on Geometric Representation Theory at Oberwolfach in April 2022.

Notes for the second part of my course on Langlands correspondence and Bezrukavnikov's equivalence. This course finished in July 2020, ending nowhere near where I thought it would
