About me
I am an assistant professor in the Statistics group (STAT) in the Department of Applied Mathematics, at the University of Twente. I work on problems and solutions in machine learning and statistics. My research focuses on hypothesis testing, Bayesian learning and best-arm identification problems. Currently I work on my VENI project 'E-values for Multiple Testing’. Central in my work is both bringing a solid mathematical foundation to the topics I work on in different fields, as well as making the theory accessible for less mathematical audiences. I’m also interested in the mathematical and philosophical foundations of Bayesianism, machine learning, statistics and probability theory.
I wrote a column for NAW about my view on statistics as a field and where it should go: a paradigm shift (PDF).
Before coming to the University of Twente, I was an assistant professor at the Vrije Universiteit Amsterdam. Until my family moves north/east, I'm very grateful for the flexibility of the University of Twente to work partly remotely, and for LUXs Data Science in Leiden, and CWI and VU Mathematics in Amsterdam to welcome me as a guest researcher and to let me use their facilities.
I’m committed to DEI and want to contribute to academia being a workplace where everyone feels valued and can be themselves. Be welcome to have a chat with me about it. I started an intiative for propagating kindness in academia (news article UToday, website).
Outside of work, some easy topics for conversation are: running, cycling, swimming (I completed my first triathlon in May), hiking, training dogs, raising kids, languages, classical music, and much more!
