His appointments include positions at universities and research institutes across Poland and Europe, collaborating with groups in algorithmic graph theory, parameterized complexity, and logic in computer science. He has participated in research projects funded by national and European agencies, contributing to consortia that include researchers from institutions such as the University of Warsaw, Royal Institute of Technology, and other leading centers. Cygan has served on program committees for conferences in algorithms, complexity, and automated verification, and has been a reviewer for journals covering theoretical computer science and formal verification.

Research contributions and publications

Cygan's research spans parameterized complexity, exact and approximation algorithms, and formal methods for system verification. He has authored and coauthored papers addressing problems such as Steiner Tree, vertex cut, feedback vertex set, and counting problems in graphs, contributing fixed-parameter tractable algorithms and kernelization results. His publications appear in conferences and journals including venues for algorithms and complexity, and he has collaborated with prominent researchers in the field.

Notable research topics and results include work on parameterized algorithms for connectivity problems, randomized and deterministic methods for small solutions in graphs, and algorithmic lower bounds informed by complexity-theoretic hypotheses. He has contributed algorithms that exploit combinatorial structures in sparse graphs, and has investigated trade-offs between preprocessing (kernelization), branching, and dynamic programming over tree decompositions. His work also touches on algebraic techniques for exact counting, meet-in-the-middle strategies, and fast subset convolution methods applied to classical NP-hard problems.
