I am a PhD student at the Faculty of Mathematics and Physics at the University of Ljubljana in Slovenia working under the supervision of Luka Boc Thaler. I am also a young researcher at the Institute of Mathematics, Physics, and Mechanics in Ljubljana.
Research wise I am interested in complex analysis and complex dynamics.

Since 2023 I am lecturing at summer and winter schools for high school students organized at the University of Ljubljana. Here is one of the most recent one.
Autumn Term 2024: Teaching assistant for Analysis 1 - Financial mathematics
I completed my Bachelor's and Master's degrees (2019-2022 and 2022-2024 respectively) in mathematics at the Faculty of Mathematics and Physics at the University of Ljubljana in Slovenia.
My Bachelor's thesis is titled Quasiconformal surgery and Herman rings. The thesis covers the construction of a rational map with a Herman ring using quasiconformal surgery. It received the faculty Prešeren award in the year 2022. (thesis)
My Master's thesis is titled To Runge approximation via quasiconformal folding. The thesis is on quasiconformal folding and how it can be used to show an improved version of the classical Runge approximation theorem, which gives additional control over critical values and critical points of the approximating polynomial. It received the faculty Prešeren award in the year 2024. (thesis)
