Jason Long

I used to be a Postdoctoral Researcher in mathematics at the University of Oxford, working with Professor Peter Keevash. I was also a Stipendiary Lecturer at Mansfield College. Before this, I was a PhD student in DPMMS at the University of Cambridge under the supervision of Professor Tim Gowers

I now work in industry, where I started at J. P. Morgan AI Research working in the area of Explainable AI, and then moved again to work at Squarepoint Capital. I still think about maths whenever I can find the time.

Research Interests

Research-wise, I am mostly interested in combinatorics, particularly extremal and probabilistic graph theory and problems on hypergraphs.

I have also worked on the interface between combinatorics and algebra, mostly on problems related to character theory of Sn.

More recently I have worked in AI on explainability and optimisation.
