I am a fourth year PhD student in the Perimeter Institute for Theoretical Physics in Waterloo (Canada), where I work on theoretical cosmology with Neil Turok. I received bachelor and master degrees in Physics, Astronomy, and Mathematics from the University of Groningen (the Netherlands) in 2012 and 2014. I subsequently received a master degree in Applied Mathematics (Part III) from the University of Cambridge (the United Kingdom) in 2015.

I am generally interested in the application of abstract mathematics in theoretical physics to further our understanding of observations and the workings of our universe. During my bachelors and masters in Groningen, I applied homology and catastrophe theory to the late time universe. Currently, I use geometry and Picard-Lefschetz theory to study quantum cosmology and the formation of shocks in the early universe.
