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 problems and solutions in machine learning and statistics. My research focuses on hypothesis testing, Bayesian learning and pure exploration 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 hugely enjoy working with my group on a selection of these topics.
I am a member of the Young Academy Twente and the EMS Young Academy. I am 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).
I am an ELLIS member. My current work and part of my group is funded by NWO VENI and M2 grants. I am a member of the Round Table Mathematics Round Table Mathemnatics, and Associate Editor of JRSS-B.
Outside of work, some easy topics for conversation are: triathlon, hiking, training dogs, raising kids, languages, classical music, and much more!
