About me

I am a very friendly person, enjoying music, sports (anything involving a ball), board games (currently very much into Dune Imperium board game) and other social activities. I like travelling and exploring. I am an avid learner, especially about topics I never studied before.

Currently, I work as an AI research scientist at DeepL, focusing on improving our reinforcement learning efforts for aligning our LLMs closer to the customer's needs. Fun fact about the job is that I read many more papers nowadays than I had in the latter half of my PhD, hence the pace of learning is quite quick and the incorporation of the cutting-edge research into our codebase is done with utmost alacrity.

Before this, I was a postdoc at the Max Planck institute for astrophysics in Garching, Germany. Focus was on binding the developed code-base from the C++ environment into python (read JAX), in order to utilize the capabilities of numpyro library, and automation of chain convergence diagnostic also developed during my PhD.

I did my PhD at the Max Planck institute for astrophysics in Garching, Germany with Fabian Schmidt. Work was focused on the development of novel Bayesian forward modelling approaches for extracting useful cosmological information from the large-scale structure data, utilizing the effective field theory of structure formation. I am also a part of the Aquila consortium, and have contributed to several projects within the consortium. You can access my PhD thesis here.

My master thesis work was done at the same institute, however in the group of Torsten Ensslin, with additional mentoring from Reimar Leike. This was within the theoretical physics master program at the Ludwig Maximilians University in Munich. I focused on learning about the connections between differential geometry and learning algorithms, modelling causal relationships within bivariate datasets and quasi-periodic signal extraction using Gaussian processes with the NIFTy package. From this thesis, several publications arose as a result and several enhancements of the package itself. The thesis itself is available at these overleaf coordinates. The accompanying code can be found on my github repo.

I finished my Bachelor studies in Belgrade, Serbia at the Belgrade University, Faculty of mathematics. I focused on theoretical physics and astrophysics classes. Student's are not obliged to submit a bachelor thesis at the end, however I myself tried to do a small research project every summer. I listed all those projects below in the Unpublished projects section.
