About Me
I am a PHD student and a researcher at TU Dresden and at University of Wrocław, supervised jointly by Sebastian Rudolph (Dresden) and Emanuel Kieroński (Wrocław). Before joining TU Dresden I studied "Parisian Master of Research in Computer Science" at ENS Paris-Saclay, under the supervision of Stéphane Demri.
My works focus on different aspects of ontology mediated data access and applications of decidable fragments of first-order logic (like existential rules or guarded-fragments) to database-inspired reasoning problems. More broadly, I'm interested in finite model theory. Since April 2019 I am employed in the ERC grant DeciGUT. Moreover, from September 2018 until September 2022 I was a principal investigator in my own Polish Ministry of Science and Higher Education grant titled "Logics with generalized counting quantifiers for data-aware processes and database systems".
One of my biggest passions is teaching. I actively contribute to an introductory logic course at the University of Wrocław (as a problem setter, organiser of exercise sessions, and supplementary lecturer). From time to time I also organise classes related to finite model theory (both in Wrocław and Dresden), so feel free to contact me if you are interested in doing some research projects (BSc/MSc/PHD) in related areas! At the beginning of 2022, I kick-started a teaching company and started teaching some classes in the XIV highschool in Wrocław.
