Niek Tax

Research Scientist

I am a Research Scientist at Meta in the Statistics & Privacy team, where I work on applied research problems in the space of causal AI and causal inference. Research topics that interest me include heterogeneous treatment effect estimation, off-policy evaluation, (adversarial) robustness, online learning, and ranking. Previously, I worked on applied machine learning for fraud detection at Booking.com. I have a PhD degree in process mining from Eindhoven University of Technology, under supervision of Prof. W.M.P. van der Aalst.
