Epiwork Final Project Meeting

Wednesday, May 29, 2013

This fourth and last project meeting is not only the usual check point of the activities of the project within the consortium but also, more importantly, as a moment to assess the final integration effort and  joint research among the partners and among the Work Packages, in preparation for the last review  meeting. The meeting will allow, as the previous years, all partners to provide a summary of the  activities undertaken and the progress of the research activities.
