Theoretical computer science.

Research in theoretical computer science

I am broadly interested in theoretical computer science, with a focus on constraint satisfaction problems and parameterized complexity.

My research is in computational complexity, an area that studies possibilities and limitations of efficient computation from a mathematical perspective. More specifically, I work on constraint satisfaction problems – a general class of problems where a global solution needs to satisfy many local constraints (think of solving the Zebra puzzle, or scheduling classes for a university while avoiding time conflicts).

Short facts about George Osipov 

I am a fourth-year PhD student at TCSLAB supervised by Peter Jonsson and co-supervised by Victor Lagerkvist. 
Originally I'm from Georgia where I received a BSc in computer science at Free University of Tbilisi and studied towards a MSc in mathematics Ilia State University. 
I spent a year at Uppsala University thanks to the Erasmus+ exchange programme. I am part of AIICS division at IDA and also AI/math track of WASP graduate school.
