Matt and Allison attended a Dagstuhl Seminar on Geosensor Networks. The Schloss Dagstuhl Leibniz Center for Informatics in Germany is one of the leading centers for informatics in the world, with a long waiting list to host seminars. Matt was one of the organizers of the seminar, entitled: Geosensor Networks: Bridging Algorithms and Applications. The week-long seminar brought together researchers from around the world with expertise in the theory, design, and deployment of geosensor networks for an intensive collaboration. The aim of the seminar was to foster better knowledge transfer from theoretical approaches to geosensor networks through to practical applications, such as that being attempted in the RISER project.
