Message of the Coordinator

We are getting closer to the end of the semester but before that, we have one major DYSCO activity to go.
The next DYSCO Study day is organized by the UCL team and takes place on Thursday May 19, 2016 at the Hotel Ibis Styles in Louvain-la-Neuve.
The programme is now finalized and the abstracts are available online (see below). As announced before, we are trying out a new format where posters sessions are replaced by a "speed dating" session. Find out what it is about by participating !

I hope to see many of you there.
