Hej, I am Matthias!
Hej, I am Matthias!
Currently, and potentially for the rest of my life, I am a mathematician who has fallen in love for discrete algorithms. So far, I spend most of my research on questions related to Online Algorithms (see my Research page for some overview).
As I believe that theoretical computer science or math are some of the most beautiful things in life where you can spend time in, I also used to spend a decent amount of time to convince others that those topics are great (see my Teaching or Thesis page for some details).
So if you are interested (or are open to become interested) in combinatorial algorithms or related questions, just hit me up!
Since July 2026, I am working as a postdoctoral researcher in the Algorithms Group at Syddansk Universitet (SDU), hosted by Lars Rohwedder.
Before, I was a research and teaching assistant in the Group for Theoretical Computer Science at RWTH Aachen from 2021 to 2026. I received my PhD in March 2026 with a thesis about online computation, advised by Peter Rossmanith .
