Matthijs van Leeuwen
Matthijs van Leeuwen is a former member of the ADA group. He currently holds a post-doctoral researcher position in the Machine Learning group of the Katholieke Universiteit Leuven, you can find his current web page here.
Matthijs was a Ph.D. student in the ADA group from September 2005 to December 2009 and defended his thesis 'Patterns that Matter' on February 9th 2010. After that, he became a postdoc working on the Exceptional Model Mining (EMM) project in the same group. In September 2011, he left the group and started in Leuven.
