My main area of research is that of data management. Currently, I am mostly interested in data management and query evaluation in a distributed context. In the past, I worked on
datamining in bioinformatics, XML schema inference, and logic in databases. Most of my publications can be found on DBLP, Google Scholar or DSPACE. Some papers can be found on PubMed.

I serve on the editorial board of
Theory of Computing Systems.
I am actively working on the introduction of appropriate computer science education for all Flemish pupils from age 6 to 18. More information can be
found in the recent publication by the Belgian Academy of science entitled
