Preprints:

• Igusa stacks for certain abelian-type Shimura varieties (arxiv)

• Oort's conjecture for split unitary Shimura varieties (with Paul Philippe and Eva Viehmann) (arxiv)

Other activities:

• In April 2026, I organized a Kleine AG at the University of Münster. Its theme was the construction of Rapoport-Zink spaces and proving the p-adic uniformization theorem. The announcement can be found here, and a more detailed syllabus can be found here.

• Together with Eva Viehmann, I organized the Oberseminar of the Arithmetic Geometry group in Münster in summer 2026. Its theme was the construction of Igusa stacks for Siegel-type Shimura varieties and using them to prove Mantovan's product formula. A program outline can be found here.
