I am Assistant Professor with the Web Information Systems group, at the Delft University of Technology. I am faculty fellow with the IBM Benelux Center of Advanced Studies.
My research lies at the intersection of crowdsourcing, user modeling, and web information retrieval. I study and build novel Social Data science methods and tools. My goal is to help improving well-being and fostering inclusion by means of Web-based, personalized social computing systems that combine the cognitive and reasoning abilities of individuals and crowds, with the computational powers of machines, and the value of big amounts of heterogeneous data.
