This conference in Denmark looks really interesting for anyone interested in Systems and Network Biology. The organizers have done a great job in getting together a good set of international speakers and it is not too expensive. Plus, May is one of the nicest months to visit Denmark. The conference venue is reasonably close to the nice beach at Snekkersten, if my memory is correct.

The only downside (for me at least) is that I won’t be able to make it!!
