A senior researcher in CWI's Database Architectures and Information Access theme (INS1), I lead the Information Access research (aka M4 team (internal)). The main topics of my research include structured document retrieval and entity ranking, multimedia information retrieval, the application of information retrieval theory to recommendation systems and social media, nearest neighbour search in high dimensional spaces, the integration of information retrieval and database technology, and the evaluation methodology needed in these novel information retrieval application areas. I am very interested into the newly proposed dataspaces abstraction.
I have been appointed Full professor Multimedia Dataspaces at Delft University of Technology!
