For a brief and compact overview, take a look at my 1-page CV.
I have been working as staff member (first as Assistant Professor and since 2018 as Associate Professor) at the Web Information Systems group, Delft University of Technology since 2013. 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 a number of PhD students I am currently focusing on how to incorporate search into the human learning process at scale, collaborative search, and conversational search. For the latter, I am also maintaining a list of conversational venues and datasets. In 2016 and 2017 I received two prestigious personal grants from 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 “search 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. In the past few years, in addition to IR, I have also been active in the area of learning analytics (data science applied to large-scale educational data traces).
In 2018, I gave an invited keynote at the French IR conference CORIA 2018 on the topic of search as learning:
In 2021, I gave an invited keynote at the MICROS workshop, co-hosted at ECIR 2021 on the topic of conversational search:
