Message of the Coordinators

The next DYSCO day will be organized by our new partner and will take place on May 16, 2014 in Namur.

The programme that the UNamur team has put together is already online (follow this link) and promises to be very interesting. The study days are an ideal opportunity for our younger researchers to interact with each other and to hear about the latest developments from well-established researchers. We urge you to attend this study day so that you can benefit from all this.

We hope to see many of you in Namur !
