About

My name is Diederik Roijers, and I am an FWO postdoctoral fellow at the AI lab at the Vrije Universiteit Brussel (VUB).

Before, I was a PhD student in the Intelligent Autonomous Systems Group at the Informatics Institute at the University of Amsterdam under the supervision of Shimon Whiteson and Frans Oliehoek. Please check out my PhD project for further details. After that I was a postdoctoral researcher in the TERESA project, at the Department of Computer Science of the University of Oxford.

My main field of interest is decision theoretic planning and learning. Other interests of mine are machine learning, evolutionary computing, e-tutoring systems and education.

If you would like to contact me please e-mail me at droijers(AT)ai[dot]vub(dot)ac{dot}be. My office is located on the tenth floor of building G of the VUB campus, at Pleinlaan 2, Brussels, Belgium.
