Recorded
August 2025, at the Summer Topology and its Applications Conference in Mobile, AL (online talk), on bounded cohomology, with a focus on transformation groups. Recording.
May 2025, at the Wroclaw Geometry seminar, on constructions of monsters with homological control, after my paper with Bin Sun on this topic. Recording.
July 2023, at ESI (Vienna) for GAGTA 2023, on Ulam stability in general, and Ulam stability of Thompson groups in particular, after my paper with Bharatram Rangarajan on this topic. Recording (the audio is not great).
November 2022, Fields Institute Toronto, for the Simons Distinguished Visitor Seminar, also on Ulam stability of lamplighter and Thompson groups, this time with a friendly introduction to Thompson groups. Recording.
March 2021, for the Stability and Testability Seminar at IAS Princeton, on ultrametric stability problems, with special attention to a p-adic analogue of Ulam stability, after my paper on this topic. Recording.
January 2021, for the International "What is?" seminar on bounded cohomology and simplicial volume, about this really cool paper which explains how to extend an alternating quasicocycle from a hyperbolically embedded family of subgroups. Recording. More details can be found in the Proceedings of the seminar.
April 2020, for the International young seminar on bounded cohomology and simplicial volume, on Brooks quasimorphisms and the more combinatorial aspects of my Master Thesis. Recording.
And here are some talks by collaborators of mine on our joint work.
Turbo Ho in June 2025, at GAGTA, about our paper joint with Rémi Coulon on the first order-theory of torsion-free Tarski monsters. Recording.
Matt Zaremsky in March 2025, at IAS Princeton, about recent progress on the Boone-Higman conjecture, with special emphasis on our paper joint with Jim Belk and James Hyde on the Boone-Higman conjecture for Aut(F_n). Recording.
