My main research interest is exploratory data mining: how can we enable domain experts to explore and analyse their data, to discover structure and ultimately novel knowledge?

The approach I take is to define and identify patterns that matter, i.e., succinct descriptions that characterise relevant structure present in the data. Which patterns matter strongly depends on the data and task at hand, hence defining the problem is one of the key challenges of exploratory data mining. Moreover, I find it very interesting to do fundamental data mining for real-world applications; there is no better way to show the potential of exploratory data mining than by demonstrating that patterns matter.
