About me

I am currently a senior research assistant (postdoc) at the Department of Mathematics, University of Zagreb, Croatia.

I got my PhD at University of Zagreb in July 2025 under the supervision of prof. Zvonko Iljazović with the thesis titled "A local approach to computability of quotient spaces".
