I am the head of the database technology group at the Department of Informatics (ifi) at the University of Zürich. My research interests include various aspects of data management, and have focused on time-varying information, data warehousing, similarity search in databases, and data analysis. My work has a technological focus and includes the construction of data-centric systems, query processing, data modeling and query languages, and systems architectures.
Before joining the University of Zürich I was employed at the computer science departments of the Free University of Bozen-Bolzano (2003-2009), Aalborg University (1995 - 2003), University of Arizona (1994 - 1995), and ETH Zürich (1990 - 1994). At the Free University of Bolzano I was the head of the Faculty of Computer Science from August 2003 until September 2007. I was a lecturer at the Engineering School in Grenchen, Switzerland (1990 - 1994).
