  A series of Winter Schools aimed at doctoral students and young researchers, co-organized each year since 2012 in Enney or Charmey (Switzerland) with Jérémy Blanc (Basel) from 2012 to 2016. Starting from the 6th Edition 2017, the school is now mainly co-organized by S. Zimmermann (Angers), R. Terpereau (Dijon) and P. Habegger (Basel). Each edition is centered around 3 mini-courses on current trends in Algebraic Geometry given by invited senior researchers, completed by a series of more specialized talks given by younger participants.

  A series of joint mini-workshops in Algebraic Geometry initiated with Jérémy Blanc (Basel) in 2015 and held until 2017 on a biannual basis between the Institute of Mathematics of the University of Basel and the University of Burgundy. In 2017, the series became the Basel-Dijon-EPFL Joint Seminars organized with the additional partneship of the Mathematics section of the École Polytechnique Fédérale de Lausanne. The regular meetings are mainly co-organized by Jérémy Blanc (Baseal), Ronan Terpereau and Adrien Dubouloz (Dijon) and Zsolt Patakfalvi (EPFL).

Research Networks or Projects I have been involved into.

• GDR CNRS n°3064 - Géométrie Algébrique et Géométrie complexe
• GDR CNRS n°2945 - Singularités et Applications
• GDR CNRS n°3395 - Théorie de Lie Algébrique et Géométrique
• GDR CNRS n°2875 - Théorie de l'homotopie et applications
• The Informal Affine Algebraic Geometry Network

  An informal (and unstructed !) network of european researchers around the themes of Affine Algebraic Geometry. This network has its root in the French-Swiss study group Automorphismes des Espaces Affines" started in 2006. It progressively grew up into a larger network with broader interests in Algebraic Geometry and its interactions with commutative algebra, holomorphic dynamics and geometric group theory. Its activities temporarily merged with those of the ANR Project "BirPol" for the period 2012-2016.
