Dries Van Dyck Theoretical Computer Science Group Department of Mathematics, Physics and Computer Science Hasselt University, Transnational University of Limburg Starting from October 1, 2010, I will leave Hasselt University and join the Nuclear Systems Research group, an expert group of the Advanced Nuclear Systems institute at the Belgium Nuclear Research Centre (SCK-CEN). At SCK-CEN I will join the R&D-effort to develop an ultrasonic visualization system for liquid metal in the framework of the MYRRHA-project. Click here for contact information at SCK-CEN.

Research Projects

• Database support for similarity in biological networks (co-promotor), PhD studentship of Peter Boyen, together with Frank Neven (main promotor), funded by Institute for the Promotion of Innovation through Science and Techonoly in Flanders (IWT-Vlaanderen)
• Graph Logic (co-promotor), together with Jan Van den Bussche from our group and Hendrick Blockeel (main promotor) and Jan Ramon from the Department of Computer Science of KULeuven, funded by Research Foundation Flanders (FWO)
