Research Interests

I always loved everything that has to do with logic. Since the third grade I was member of a chess club and I played in tournaments for several years. In high school I was competing at the Mathematical Olympiad, winning multiple prices in the national rounds. That also let me be part of JuMa (Youth trains maths) which got me into contact with some cool concepts of maths that you normally learn much later.

After high school I decided that I want to do something more practical than pure maths, so I studied computer science. I quickly went back to the theory side but the more practical things I learned are still very useful to implement some of the ideas I have and test them on examples.

My current focus is mainly on randomized processes and algorithms. Finding patterns in seemingly random things and juggling with expectations and probabilities is quite fun and challenging. However, I am also drawn towards other topics of theoretical computer science which makes it rather hard to commit to a specific direction for future research.
