Small Bio

Currently a postdoctoral researcher of computer science at The University of Warsaw, Poland (since 2022), in the group of Wojciech Czerwiński.

Previously I was a postdoctoral researcher at The Max Planck Institute for Software Systems (MPI-SWS), Saarbrücken (2020-2022), in the group of Joël Ouaknine. I completed my PhD in computer science at the University of Warwick in 2020, supervised by Andrzej Murawski, Dmitry Chistikov and Graham Cormode, funded by EPSRC as a member of the Centre for Doctoral Training in Urban Science and Progress. Before that, I obtained a BSc in Discrete Mathematics and a MSc in Data Analytics, both from the University of Warwick.

I am currently the co-ordinator of SIGLOG Monthly, a monthly newsletter for logic related happenings in computer science, send your call for papers and other announcements to
