I obtained my PhD in June 2013 under the supervision of J.-B. Bost (Paris-Sud 11), Bas Edixhoven (Leiden), and Robin de Jong (Leiden). From July 2013 until November 2015 I was a post-doctoral fellow supported by the SFB/Transregio 45.

Autumn School 2017: Topics in arithmetic and algebraic geometry

This autumn school is organized by Davide Cesare Veniani, Dino Festi and myself with the help of SFB/TRR 45 Bonn-Essen-Mainz and will take place in Mainz from October 9th until October 13th, 2017.

Summer School 2015: Algebraic Stacks

This summer school was organized by Ronan Terpereau and myself with the help of SFB/TRR 45 Bonn-Essen-Mainz and took place in Mainz from August 31st until September 4th, 2015. The website contains live-teXed notes for most of the lectures.
