PhD Candidate in Theoretical Cosmology at the University of Groningen, the Netherlands.


I’m a PhD candidate at the University of Groningen in the Netherlands. I work primarily on the use of late time cosmological probes, such as galaxy surveys and intensity mapping (e.g. 21-cm) to study the primordial universe, in particular cosmic inflation and primordial non-Gaussianity. In my research I make use analytical as well as modern machine learning methods. Besides this, I like to think about formal aspects of cosmology such as consistency conditions and the cosmological bootstrap. Recently I have also been studying the amplitude double copy and its connection with massive gravity.

My PhD research is part of the Fundamentals of the Universe program and my advisors are Dr. Daan Meerburg and Prof. Diederik Roest at the Van Swinderen Institute for Particle Physics and Gravity and Prof. Léon Koopmans at the Kapteyn Astronomical Institute.
