The swiss isogeny day is a recurring meetup of cryptographers working on isogeny-based cryptography in and around Switzerland.
In the past we have had attendees from ENS de Lyon, EPFL, Ethereum Foundation, ETH Zurich, IBM Research, Politecnico di Torino, Ruhr-Universität Bochum, Technische Universität München, Universität der Bundeswehr München, Universität Konstanz, Université Côte D'Azur, Universiy of Colorado Boulder, and UZH.
No date set yet for the next event.
