Teaching
Currently I the 3rd year B. Sc.course Linear Analysis at Leiden in the fall semester, and the Mastermath course Operator Algebras (together with Martijn Caspers, Delft) in the spring semester. In the spring semesters of 2021-2023 I taught the course Differentiable Manifolds (now taught by Emre Sertoz), and in the fall of 2023 I gave several lectures for the Mastermath course Functional Analysis (taught by Marcel de Jeu and Onno van Gaans). These courses are foundational to many areas of mathematics. In particular, they together provide a good starting point to get into noncommutative geometry.Contact
