I am an Assistant Professor in the Department of Mathematics and Computer Science at TU/e. Previously, I was a Ph.D. candidate in the Algorithmics Group at Delft University of Technology, advised by Dr. Matthijs Spaan. Next, I was a PostDoc researcher with the Department of Software Science (SWS) at Radboud University Nijmegen advised by Dr. Nils Jansen. For more details, checkout my biography or my cv .

Research Interests:

The motivation for my research revolves around making AI techniques more reliable, to enable their deployment in real-world applications. I focus on developing AI algorithms for scenarios with constrained interactions with an unknown environment. I am currently interested in safe reinforcement learning, a research topic concerned with problems where a minimum performance must be guaranteed and catastrophic events must be avoided.
