Currently, I lead the Intelligent Systems Lab Amsterdam. ISLA is composed of three groups. The IAS group researches intelligent autonomous systems and the ILPS group investigates information and language processing. The Intelligent Sensory Information Systems group, ISIS, conducts research in the theory, practice, and implementation of multimedia information analysis. In this group, my scientific interest is in computer vision, content-based image and video retrieval, tracking, learning, and pictures and language. ISIS has an extensive record in co-operations with Dutch industry and long-term relations with the Nederlands Instituut voor Beeld en Geluid and the Nederlands Forensisch Instituut. Since 2001, I am director of MultimediaN, a nation-wide, large program for multimedia information processing supported by the Dutch government. I am currently also director of ASCI, a nation-wide research school on computing and imaging. I am an associate editor of the International Journal of Computer Vision and of the IEEE transactions on multimedia. Since 2000, I am elected fellow of International Association of Pattern Recognition, and I am a honorary member of the Dutch Society for Pattern Recognition and Image Processing.
