I teach Topologie en Meetkunde (WISB341) and Wiskundige technieken 3 (WISN202) and I run a seminar on VOA's with Johan van de Leur. Last semester, I tought Group theory and ran a seminar on Algebraic K-theory jointly with Timan Bauer. Past teaching: Introduction to CFT, Wiskundige technieken 3, Functies en reeksen, complexe functies (most of them multiple times). Some seminars that I led in the past: von Neumann algebras (spring '11), Topological modular forms (fall '10), Operads and loop spaces (spring '09), Stable homotopy theory (fall '08), Twisted K-theory (spring '08). Link to the Utrecht staff colloquium and to the quarterly Topology and Geometry seminar.
From 2004 to 2007, I've organized the first four Talbot workshops, with C. Douglas, J. Francis, and M. Hill. They are now run by S. Ganatra, O. Gwilliam, H. Tanaka, and S. Glasman. In August 2010, I ran a workshop on Operator algebras and conformal field theory (i.e. conformal nets).

My ERC grant proposal is about the conjectural relationship between conformal nets and TMF.
It describes pretty well my research interests. Here it is: Part 1 (administrative) and Part 2 (math).
