Joint PPS - PIHOC - DIAPASoN Workshop

February 26-28, 2020

The ANR PPS kick-off meeting will take place from Feb 26 to Feb 28, 2020 at IRIF (Paris) and will be joined with the 3rd edition of the PIHOC workshop series initiated by Ugo Dal Lago in 2018 and with Dal Lago's DIAPASoN ERC project kick-off meeting.

The meeting is organized by the Institut de Recherche en Informatique Fondamentale. It will take place in the Turing conference room of the Sophie Germain building (first basement) of Université de Paris.

The invited speakers are:

  • Gilles Barthe (Max Planck Institute)
  • Fredrik Dahlqvist (University College London)
  • Barak Pearlmutter (Maynooth University)
