Attend a seminar

Information for external visitors

External visitors are welcome to join DIFFER seminars. Registration in advance is however required. If you want to visit a DIFFER seminar please:

  • Register yourself through this website (link at the bottom of the page of the seminar you are interested in) at least 1 day in advance. In this way we know how many external visitors we can expect, and whether we can accommodate everybody (seminar room size is limited).
  • On the day of the seminar, please register yourself as a seminar visitor at the reception. We can ask for identification, so please don’t forget to bring an ID card (passport, driving licence etc.). You will then get a seminar visitors badge and instructions on how to get to the seminar room. Seminar visitor badges permit access to the DIFFER building until one hour after the seminar.
