Research Interests

To specialize on a very specific scientific area is the common approach for a young scientist. However, this potentially misses great opportunities. During my PhD I discovered that two different mathematical communities had been working on the same problem for more than a decade without knowing of each other. I thus believe that it is necessary for different scientific communities to talk to each other, and to understand the others' research and goals. My general aim as a scientist is to help bridging the gap between different fields of science.

The following descriptions contain a few selected publications each. My full list of publications can be found here, and a more detailed CV here.

During my PhD at University of Saarland with Prof. Ernst-Ulrich Gekeler I worked in the intersection between number theory, algebra and probability theory:

I have since then turned to several more applied areas, including computer science and neuroscience. My greatest challenge so far was to gather enough biological background to contribute to the neuroscience community:

I also enjoy working on evolutionary (bio-inspired) algorithms for discrete optimzation. The following is a small sample of my work there:

In the last years I started working on random graph models for large real-world networks. I am proud that our model of Geometric Inhomogeneous Random Graphs (GIRGs) is now established and increasingly picked up by other authors and communities. An introduction into this fascianting topic can be found in the script for my course Complex Network Models. Central papers include:

I have also worked on various other topics in computer science and mathematics, for example:
