Wouter Zomervrucht

I am a PhD student in the arithmetic geometry research group at the Mathematical Institute of Leiden University and in the arithmetic geometry research group at the Mathematical Institute of FU Berlin, supervised by Bas Edixhoven and Hélène Esnault. My stay in Berlin was supported by the Berlin Mathematical School and the IRTG Moduli and Automorphic Forms.

I obtained my master's degree at Leiden University in November 2013 with a thesis on descent of curves.
