About me
I am Nikola Jovanović, a PhD student at the Department of Computer Science, ETH Zürich. I am part of the Secure, Reliable, and Intelligent Systems Lab since January 2022. I previously obtained my Computer Science MSc at ETH Zürich in 2021, and my Computer Science BSc at Faculty of Computing, Union University, Belgrade in 2019.
