I am a PhD in the research group of Prof. Christoph Thäle located in Ruhr-Universität Bochum, Germany, where I currently work on exploring various concepts related to stochastic geometry on the 3-regular tree, most notably Poisson Line Tessellations. I currently also work the Boolean model in hyperbolic space. Scaling limits of random trees is another topic of interest to me.
I started my PhD here in Bochum in January 2026. Before that, I studied in Groningen where I did both my Bachelor and Master in general mathematics, where during my Bachelor, I focussed on abstract algebra, writing my thesis on CM-fields, a special type of algebraic field where complex multiplication is in the automorphism group. In my masters, I specialized in probability theory, writing my thesis on scaling limits of discrete aggregation trees, a natural generalization of convergence of rescaled uniformly sampled labelled rooted trees to the continuum random tree.
