I am a postdoctoral researcher at Computer Science Institute of Charles University. My research interest include combinatorics, descriptive set theory, random processes and distributed computing. From September 2026, I am leading the ERC CZ project LoGloS.

Open position on LoGloS

There is a 3-year postdoc position with starting date after 1.1.2027. For more information see the webpage of the project LoGloS, informal inquiries are welcome at grebikj@gmail.com.

Short bio

Before, I was working at Computer Science Institute of Charles University with Vašek Rozhoň (3/2026-8/2026); I was a postdoctoral researcher at Institute of Mathematics at Universität Leipzig in the group of Dan Kral (10/2025-2/2026); a Marie Skłodowska-Curie postdoctoral fellow at Institute of Mathematics at Universität Leipzig, Department of Mathematics at UCLA and Faculty of Informatics at MU (8/2023-9/2025) (you can find more details about my Global MSCA Postdoctoral Fellowship here BORCA); and a research fellow at the University of Warwick working with O. Pikhurko on the Leverhulme Research Project Grant RPG-2018-424 "Measurable Combinatorics" (10/2019-7/2023). I completed my PhD at the Charles University in 2020 working under supervision of David Chodounský.

Our research on distributed algorithms and measurable combinatorics has been highlighted by Quanta Magazine.
See also our survey with Z. Vidnyánszky From descriptive to distributed, or the great surveys of Bernshteyn, Pikhurko, and Kechris and Marks on recent development in the area.

I have recieved the Early Career Award 2025 of the European Set Theory Society.

I have recieved the 2022 Mary Ellen Rudin Young Researcher Award.
