Welcome to my homepage. I am an associate professor at the Korteweg-de Vries Institute for Mathematics at the University of Amsterdam in the Netherlands. In my research, I study the mathematical foundations of machine learning.
News
- Upcoming this semester:
- A selection of interesting papers will be presented at the NeurIPS debriefing
- We have a series of great international speakers in the Statistics and Machine Learning Thematic Seminar
- I have started blogging again.
