I am a postdoctoral researcher at the Faculty of Mathematics and Computer Science at Leipzig University, where I am hosted by Daniel Kráľ. I obtained my PhD in Mathematics at Jagiellonian University under the supervision of Andrzej Grzesik and Bartosz Walczak. My main field of interest is extremal combinatorics, with the emphasis on Turán-type problems.
Here, you can find my CV and doctoral thesis.
