I am currently a member of faculty at the CUNY Graduate Centre, where I am visiting under the Einstein Chair professorship in mathematics. Previously, I have been at Stony Brook University and MIT. From January 2022 to November 2025 I was also the lead researcher in the theory group at the VERSES Research Lab.
For a summary of my current research, see this page (/research). I am broadly interested in the machinery surrounding irregularity in topology and how it threads through complementary areas of algebra, analysis, arithmetic, and occasionally others. My primary research programme is devoted to (non-equilibrium) statistical field theory and the analysis of stochastic partial differential equations. I study the properties of structures on spaces of functions using techniques from global analysis and derived geometry, probability theory in infinitely many dimensions, Markov processes and Hodge theory on irregular domains, and most significantly the probability and statistical physics of strongly interacting particle systems. I am most often motivated by objects or questions in mathematical and statistical physics. The use of function space integrals, renormalisation techniques, and scaling limits feature heavily in my work as rich objects living in the intersection of these areas.
My articles (with bibliographic information) can be found on the arXiv or Google Scholar. Some of the talks I have given are viewable here (/talks). Advocacy and press relating to my work can be found here (/other). I maintain a blog about my work, amongst other things. I can also be found on MathOverflow and with ORCiD 0000-0002-7907-7611.
