Sergey Pupyrev

Research Scientist

I am a research scientist at Facebook. I am interested in combinatorial optimization, algorithmic graph theory, computational geometry, and code optimization. My current work focuses on developing algorithmic solutions for improving the efficiency of infrastructure. Prior to joining Facebook, I spent several years working on graph theory and computational geometry at the University of Arizona (USA), Microsoft Research (USA), and the Ural State University (Russia), where I received a PhD in Computer Science.

Interests

Graph algorithms, computational geometry, distributed computation, code optimization
