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 assertion, commitment, deniability and lying. Previously I investigated the semantic minimalism - contextualism debate and disagreement over vague predicates (genuine and faultless).
I'm the president of Komitet Nauk Filozoficznych PAN [Committee of Philosophical Sciences of the Polish Academy of Sciences] (2020-2023 and 2024-2027).
I'm the representative of my Faculty at the Philosophy of Language and Mind network and I was the organiser of the 6th PLM Conference in Warsaw (2022).
In 2024 I was awarded a 4-year National Centre for Science (NCN) research grant OPUS 25 for the project "Assertion, commitment and deniability". In the past I was PI in research grants OPUS 15 (project “Vagueness and Disagreement”) and OPUS 8 (project on sub-sentential speech acts).
In 2020, 2022 and 2024 I was a member of the ERC Peer Review Panel (StG)
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 2012/2013 I was a Fulbright Senior Advanced Visiting Scholar at the Philosophy Department at Yale University.
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.
