I currently work as Tech Lead at exnaton. In 2021, I finished my PhD in theoretical physics at Heidelberg University and the University of
Southern Denmark in
the group of Astrid Eichhorn.
Prior to that I studied in physics and information systems at Heidelberg University and
the University of Mannheim.
During my studies, I co-founded alumnii, a Software-as-a-Service
startup that offers alumni management software to companies and universities.
Selected Projects
The following selected projects are some of the projects that I have worked on in the past or that I am
currently working on.
Large networks
We analyzed random walks on real-world networks such as road-networks or biological neural networks.

I wrote a C++ code using the Stanford Network Analysis Project to efficently perform random walks on large networks and extract some of their spectral properties. We compared the resulting spectral properties to those of networks that arise in quantum gravity. For first results see this preprint.

Causal sets
Causal sets are networks describing the fundamental structure of spacetime. I wrote a code to analyze such networks using MCMC methods.
More...
Causal sets are directed acyclic graphs that describe the fundamental causal structure of spacetime. I wrote a rust code to analyze these networks using Montecarlo-Markov-chain techniques. At present the code reproduces existing results, but hopefully it should also allow to investigate exciting new questions about the role of matter in quantum gravity in the future.

Quabel
Quabel is a distraction-free text editor and publishing platform. I built Quabel together with two friends.

We built Quabel as a distraction-free editor that helps you focusing on your text and writing goals. While quabel is no longer operational, you can get an impression and read a review here.
Publications
During my PhD I worked on the interface of quantum gravity and cosmology. The following
publications are a result of that work. Notice that in theoretical high-energy-physics authors are
typically sorted alphabetically.
