Settled Optimality Of Sorting Networks From Knuth's TAOCP Vol. 3Postdoc At UC Berkeley With Sanjit SeshiaGoogle Scholar H-index 17; 1,424 Citations

Daniel Bundala is a computer scientist and software engineer at Google in Switzerland. He represented Slovakia at the International Olympiad in Informatics in 2006, winning a silver medal (rank 41), and went on to take a silver medal at the 2009 ICPC World Finals (rank 5). He completed a DPhil (PhD) in Computer Science at the University of Oxford with a thesis on algorithmic verification problems in automata-theoretic settings (2014), then was a postdoctoral researcher at UC Berkeley. His most cited research, optimal sorting networks (with Jakub Zavodny), settled the optimality of sorting networks listed in Knuth's The Art of Computer Programming.

Competitive programmer turned researcher and engineer: IOI 2006 silver medalist for Slovakia, ICPC World Finals 2009 silver medalist, Oxford DPhil in formal verification, UC Berkeley postdoc, now Software Engineer at Google.
