From November 2022, I am a postdoc in the group of David Steurer at ETH Zürich.

Previously, I was a PhD student at Centrum Wiskunde & Informatica (CWI) in the research group Networks & Optimization, under the supervision of
Monique Laurent. I defended my thesis cum laude at Tilburg University on 30 September 2022.

My main interest is in polynomial optimization and semidefinite programming approaches to hard optimization problems. Some topics I have worked on are:

• Asymptotic error analysis of sum-of-squares hierarchies.

• Extensions of the Lovász theta-number to (geometric) hypergraphs.

• Applications of reproducing (Christoffel-Darboux) kernels to topological data analysis.
