Curriculum vitae

Matthijs is assistant professor and group leader of the Explanatory Data Analysis group at the Leiden Institute of Advanced Computer Science (LIACS). LIACS is the computer science institute of Leiden University.

Matthijs likes data, patterns, algorithms, and information theory. He thinks that data mining and machine learning results should be explainable and interpretable.

Matthijs was a senior researcher at LIACS for one year before obtaining his current position. Before that, he was a postdoctoral researcher at Universiteit Utrecht for almost two years (2009-2011), working on Exceptional Model Mining, and in the Machine Learning group at KU Leuven for four years (2011-2015), where he worked on a diverse range of algorithms and applications for pattern mining and interactive data mining. He defended his Ph.D. thesis titled Patterns that Matter in February 2010, which he wrote under supervision of prof.dr. Arno Siebes in the Algorithmic Data Analysis group (Universiteit Utrecht). In this thesis, compression is used to find smalls sets of characteristic patterns that can be used for many different knowledge discovery purposes (see Krimp).
