Short Bio

I am a Lecturer (Assistant Professor) of computer science at the University of Liverpool, UK (since January 2023).

Previously I was a postdoctoral researcher at The University of Warsaw, Poland (2022), in the group of Wojciech Czerwiński and 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 through 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 one of the managing editors of TheoretiCS, a high-quality diamond open-access overlay journal. Please submit your best work.
