About me

Research Interests

I'm broadly interested in theoretical computer science and AI for mathematics.

I helped Google's 2024 IMO effort where AlphaProof achieved a silver medal standard at the mathematical olympiad 🥈. Specifically, I co-led the formalization workstream. The project was recognized by Quanta Magazine as one of the top five mathematical breakthroughs of 2024. Following this, I supported the subsequent gold medal-winning 🥇 2025 effort by contributing to formal math datasets and core research initiatives.

In theoretical computer science, I am most proud of my work on universal optimality which provides a near-complete theoretical answer to the fundamental question of: "how fast can we solve global problems like the shortest path or the minimum spanning tree in a distributed network?" My coauthors and I design distributed algorithms that perfectly (and provably so) adapt to the underlying communication network. This includes quantifying the fundamental speed limits of coordination in a network, as well as matching those limits with ultra-fast algorithms designed with user-friendly tools.

This pursuit has led to uncovering of new connections between distributed computing and many seemingly-unrelated fields of theoretical computer science: including the theory of metric embedding, information theory, parallel graph algorithms, and optimal oblivious packet routing. Notably, these connections have proven to be mutually beneficial and have led to breakthroughs on both sides.

Short Biography

I am a research scientist at Google Research in Zürich. Previously, I was a postdoctoctoral scholar at ETH Zürich, in the research group of Prof. Mohsen Ghaffari (now at MIT). I received my Ph.D. from the School of Computer Science at Carnegie Mellon University under the advisorship of Prof. Bernhard Haeupler with the thesis titled Towards Universal Optimality in Distributed Optimization. Earlier, I obtained my B.Sc. and M.Sc. from University of Zagreb under the advisorship of Prof. Mile Šikić. I like competitive programming and playing volleyball.

I am extremely honored to have received the 2021 ACM-EATCS Principles of Distributed Computing Doctoral Dissertation Award (see here and here). Earlier, I was also awarded the 2018 DFINITY Scholarship.
