I finished my PhD thesis in 2011 at the University of Warsaw, in Computer Science, under the supervision of Mikołaj Bojańczyk. My theis is available here; it concerns the limitedness problem, from the viewpoint of profinite words.

My research interests include:

• new notions of languages of infinite words – automata, logic and topological complexity
• automata over infinite alphabets.
• logic
• database theory
