/registration/index.html Registration is free but mandatory, for logistical reasons. It is open until the 8th of May, after which we cannot ensure that you will get a lunch on Tuesday. If this doesn’t scare you, you are still very welcome to register after this date to attend the talks. If you landed on this page, it most likely means that you either received the invitation email, which contains the link to register, or that you are a robot. Hugo en-us
