Welcome to my homepage. I work in the mathematics department in Utrecht University.

This term I am teaching differential geometry for third year undergraduate students. If you are attending these courses, follow the “Differential geometry” link to get information on exercise sheets, classes, marks, etc.

My area of research is differential geometry. The particular objects I work with are generalized complex structures. These were introduced by Nigel Hitchin in 2002 and are a simultaneous generalization of complex and symplectic structures. They are also physically relevant, as several objects which appear naturally in string theory arise naturally in the generalized complex world.

I am one of the organizers of the quarterly G&T seminar and I also involved in the organization of the next Poisson conference.
