Teaching
In the spring semester of 2013 I teach Algebra 3, Topologie, and Topics in Algebraic Geometry.
Activities
I am organizing the Dutch Intercity number theory seminar and the department colloquium. Recent activities include our local algebra seminar, a reading group on the Weil conjectures for K3s, a workshop on zeta functions in positive characteristic and a conference on arithmetic geometry.
