I'm a Professor of Philosophy at the Faculty of Philosophy at the University of Warsaw.
My main research interests lie in philosophy of language and metaphysics. Currently I'm working on the semantic minimalism - contextualism debate and on vagueness and disagreement (genuine and faultless). In 2013 I published a book Contextualism and vague expressions on contextual theories of vagueness (in Polish).
I'm the president of Komitet Nauk Filozoficznych PAN [Committee of Philosophical Sciences of the Polish Academy of Sciences] (2020-2023).
In 2019 I was awarded a two-year research grant (National Centre for Science (NCN) Research Grant OPUS 15 (project “Vagueness and Disagreement”)). My previous three-year NCN OPUS 8 grant awarded in 2015 was on sub-sentential speech acts.
In 2020 I was a member of the ERC Peer Review Panel.
In 2019 I was on the scientific committee of SPE 11 - The 11th Semantics and Philosophy in Europe Colloquium, Warsaw, 20-22 September 2019.
In 2019 I was the chair of the Semiotics and Philosophy of Language section at Polski Zjazd Filozoficzny (Lublin, 9-14.09.2019).
In years 2006-2012 I coordinated the English-language programme Philosophy of Being, Cognition and Value (current name: Warsaw International Studies in Philosophy) at the University of Warsaw.
I'm a member of the board of Polskie Towarzystwo Semiotyczne.
