About me

Hi, I'm Niels Holtgrefe! 👋

I am a PhD candidate at the Delft Institute of Applied Mathematics of the TU Delft in the Netherlands. I work in the Discrete Mathematics & Optimization group under the supervision of Dr. Leo van Iersel.

My research is focused on algorithms and mathematical theory of phylogenetics: the study of evolutionary history of organisms. I also work on parametrized complexity, specifically concerning the parameter scanwidth. Writing software and applying algorithms to real-world data is also something I enjoy doing.

In the fall semester of 2024 I was a visiting researcher at ICERM, Brown University (Providence, RI, USA) as part of the semester program on Theory, Methods, and Applications of Quantitative Phylogenomics. Previously, I obtained my MSc and BSc degrees in Applied Mathematics at TU Delft, both with cum laude distinction.
