About me
I am an Associate Professor of Mathematical Statistics and Chair of the Statistics group (STAT) at the University of Twente, and a Researcher in the Machine Learning group at the Centrum Wiskunde & Informatica.
I work on mathematical statistics and machine learning, especially hypothesis testing with e-values and anytime-valid inference, multiple testing, Bayesian learning and pure exploration. Much of my work is about developing rigorous theory for more flexible ways of learning from data, and making that theory accessible beyond mathematical statistics.
I also care strongly about academic culture, supervision and creating an environment in which ambitious research and kindness can coexist. More about me.
News
