Sep 05, 2026 The new Julia package DiagrammaticHecke.jl is finally out. You can now compute with morphisms in the diagrammatic Hecke category in type \(A_3\). More types are coming.
Sep 02, 2026 Back from Uppsala, where I gave a talk on circular leaves for the diagrammatic Hecke category in type $A_3$ — the slides are on my talks page. The Julia package DiagrammaticHecke.jl that grew out of this work is coming soon.
Jul 23, 2026 Last minute summer update. On August 5, I will speak at TU Berlin in the Seminar der Arbeitsgruppen Diskrete Mathematik/Geometrie & Diskrete Geometrie about “Circular double leaves in the diagrammatic Hecke category”.
May 26, 2026 The summer plan is set. The season starts with the International Workshop on Quantum Groups, Categorification and Related Topics in Kunming, China (June 7–12). In June, one will probably encounter me giving a talk at Oberseminar Darstellungstheorie at the University of Bonn on June 26. Later in the summer, you can meet me at Future Directions in Tensor Categories (Bonn, Germany, Aug 17–21) and Tensor Categories in Representation Theory & Vice Versa (Uppsala, Sweden, Aug 24–27).
Feb 06, 2026 Great news! Our paper “The center of the asymptotic Hecke category and unipotent character sheaves” (joint work with Ulrich Thiel) has been accepted for publication in Representation Theory.
Jan 12, 2026 Speaking at the Mini-conference: Categorification at the University of East Anglia, Norwich. Thank you to Vanesa Miemitz for the invitation!
Dec 02, 2025 Speaking in the Topology Seminar at the University of Zurich. Thanks to Luke Conners for the invitation!
Nov 07, 2025 Successfully defended my PhD “Asymptotic Hecke Categories” at RPTU Kaiserslautern–Landau! More details here.
