I have served on the programme committees of VLDB (2007, 2005, 1999), SIGMOD (2009, 2004), ICDE (2009, 2008, 2005, 1998), EDBT (2009, 2008, 2000, 1998), SIGSPATIAL (2010, 2009), ADBIS (2007), BTW (2007), CIKM (2010, 2005), IDEAS (2004, 2003, 2002, 1999), TIME (2007, 2002, 2001), SSTD (2003), and WISE (2002, 2001). I am a member of ACM and IEEE CS.
I have been a co-organizer of the 8th EDBT Summer School that was held at the Free University in Bolzano in September 2007. I was a co-organizer of a series on international workshops on visual data mining: 1st International Workshop on Visual Data Mining in conjunction with ECML/PKDD 2001, 2nd International Workshop on Visual Data Mining in conjunction with ECML/PKDD 2001, 3rd International Workshop on Visual Data Mining in conjunction with ICDM 2003. I am a co-editor of Visual Data Mining - Theory, Techniques and Tools for Visual Analytics, Springer 2008.
Co-principal investigator of the MEDAN competence center for Medical Data Warehousing and Analysis. MEDAN is a four-year competence center in the Database and Information Systems group in the Faculty of Computer Science at the Free University of Bozen-Bolzano. The competence center closely collaborates with Hospital Meran to realize a data warehouse that forms the backbone of a data analysis platform that supports the development of value added services for the health district South Tyrol. The center's mission is to conduct basic and applied research in the area of data warehousing and intelligent data analysis for health care and medical applications.
Member of TimeCenter, an international center for the support of temporal database applications on traditional and emerging DBMS technologies. One of the main goals of TimeCenter is to provide the foundations for developing temporal database technology that is expressly technology transferable.
Principal investigator and scientist-in-charge of the 3D Visual Data Mining (3DVDM) project. The 3DVDM project was an interdisciplinary research project funded by the Danish research council. It included participants from the Department of Computer Science, the Department of Mathematical Sciences, the Faculty of Humanities, and the Department of Electronic Systems at Aalborg University.
Co-investigator and site responsible for the COSPA project. COSPA is a consortium for studying, evaluating, and supporting the introduction of Open Source software and Open Data Standards in the Public Administration. COSPA was funded by the EU under the FP6 programme (IST-1-002614).
