Assistant Professor

Web Information Systems, TU Delft


  • I have a postdoc position on algorithmic biases available in a joint project with the University of Amsterdam. Check out the vacancy and apply by November 15, 2017!
  • The Search as Learning Dagstuhl Seminar I co-organized earlier this year was a success! I wrote a blog post on some of the challenges we identified.
  • I have spent my summer ‘17 at Blendle, a Dutch online news platform startup, and tinkered around with their search.
  • I have been awarded an NWO VIDI grant for my proposal SearchX: Integrating search and sensemaking into large-scale open online learning; this means funding for 2 PhDs and 1 postdoc position. Vacancies will be announced in early fall 2017. If you are looking for an IR PhD/postdoc position contact me!
  • I attended ICLR in April ‘17 and wrote a blog post about it.


Since 2013, I have been working as Assistant Professor (tenured as of 01/2016) at the Web Information Systems group, Delft University of Technology. Between 2011 and 2012 I was a Postdoc in the same group. I received my PhD in 2010 from the University of Twente, where I worked in the Human Media Interaction group. The Otto-von-Guericke University of Magdeburg in Germany was my home during my undergraduate years as a student in computer science. In the past, I have worked on a variety of topics in the fields of information retrieval & data science, including query performance prediction (the topic of my PhD thesis), social search, computational social science, learning to search and IR for specific user groups.

I have diverse research interests and am always happy to dive into a new area. Together with four PhD students I am supervising (Guanliang Chen, Yue Zhao, Felipe Moraes and Dan Davis), I am currently focusing on large-scale learning analytics and how to incorporate search into the learning process at scale. In 2016 and 2017 I have been awarded two prestigious personal grants by the Netherlands Organisation for Scientific Research (NWO) with a total funding of more than 1 million euros; this translates into 4-5 PhD/postdoc positions in the developing “serch as learning” research area; take a look at the Dagstuhl Seminar I co-organized on the topic to get an idea of what it is about. TU Delft is a very active provider of Massive Open Online Courses (MOOCs) on the edX platform, which provides a rich experimental playground for my Lambda-Lab team. To get a quick overview of the kind of questions we have recently published about, take a look at the following slides, they cover each contribution in 1-2 slides (check the speaker notes as well):
