Yann Régis-Gianas was multimedia chair of the organising committee of POPL 2017 that took place in Paris in January 2017.

Yves Guiraud, Philippe Malbos and Samuel Mimram have organised the third edition of the Higher-Dimensional Rewriting and Algebra (HDRA) workshop of the Formal Structures for Computation and Deduction conference (FSCD), held in Oxford in September 2017.

Yves Guiraud and Samuel Mimram, with Dimitri Ara (Univ. Aix-Marseille) have organised the “Categories in Homotopy and Rewriting” one-week international conference, at the CIRM, in Marseille, in September 2017. As the closing conference of the Cathre ANR project, focused on higher-dimensional algebra, this conference attracted 80 participants, working in category theory, algebraic topology, logic and theoretical computer science.

Matthieu Sozeau co-organised with Nicolas Tabareau the 3rd Coq Implementors Workshop in Le Croisic, France, June 12-16 2017. It included presentations from developers, both from France and abroad and a large amount of hacking.
