| Maurice van Keulen |
Maurice van Keulen is assistant professor with the database group of the University of Twente. He
studied computer science at the University of Twente and received his Msc. in 1992. His
work as a research assistant in the ESPRIT project IMPRESS gradually shifted towards PhD
research, which resulted in november 1997 in a PhD with a thesis entitled "Formal
operation definition in object-oriented databases". From august 1997 until april 1999,
he worked with the company Ordina Utopics Front Office B.V. as an information
architect. His subsequent assistant professorship at the University of Twente was
interrupted for 9 months in 2002/2003 for a sabattical with the DBIS-group at the University of
Konstanz, Germany. His research interests center around developing generic
and efficient data management for non-traditional database applications or
non-traditional use of a DBMS. Topics include XML databases, schema and data
integration, uncertainty in data, data quality, data heterogeneity, semi-structured
data, (multimedia) information retrieval, DBMS extensibility. |
