About me

I'm primarily a legal scholar. My doctoral dissertation was devoted to proxy crimes, an often-overlooked category of criminal offences, which I analysed from several perspectives: legal doctrine, moral philosophy, economic analysis of law, and experimental jurisprudence. My other main areas of interest in law are legal interpretation and judicial decision-making. Outside law, I have occasionally published in bioethics and experimental moral philosophy.

I'm currently the PI of an NCN OPUS project on "Ignorance of Law: A Study in Experimental Jurisprudence.” I've been fortunate to work with a team of talented young scholars, with whom we are trying to probe people's intuitions about questions such as: What does it mean to be ignorant of law? What epistemic duties regarding law are there? How is ignorance of law different from ignorance of other social norms, or from ignorance of facts? Check this manuscript for a representative sample of our research.

Studying ignorance of law has led me to broader questions in legal and social cognition. How do people recognise that a situation is governed by social rules? How do they reconstruct those rules from scattered environmental cues? And when do they decide it is worth investing effort to investigate potential norms? I aim to explore these questions through behavioural experiments.

Much of my research belongs to experimental jurisprudence: employing experimental methods of social sciences to generate insights useful for legal theory. I'm very fond of the experimental jurisprudence community and grateful for the support I've received from many of its leading members. In return, I aspire to expand the field's methodological repertoire. While vignette surveys remain dominant, I believe other tools—such as behavioural, multi-player experiments—can better capture the fundamentally social character of law.

The other leg of my current research involves applying natural-language processing (NLP) and large language models to extract philosophical insight from large document collections, both formal (e.g. judicial opinions) and informal (e.g. Reddit posts). Much of this work examines the history of American legal interpretation, as revealed in the corpus of U.S. federal court opinions. However, I'm eager to analyse corpora from other legal systems—feel encouraged to reach out if you have a research idea!

I was born and raised in Busko-Zdrój, in a remote yet charming corner of central Poland. By now, however, I've spent most of my life in the ancient Polish capital, Kraków. Together with my wife and our kids, we reside in the Cracovian neighbourhood of Krowodrza. Whenever we can, we like spending time in my wife's hometown.

In my spare time, I most enjoy cooking, baking, mixing drinks and other beverages, hosting guests, as well as anything aquatic.

One of the best things about Kraków is its vibrant community of legal and moral philosophers. Check the websites of the Interdisciplinary Centre for Ethics and the Jagiellonian Centre for Law, Language and Philosophy for upcoming events (most are streamed online) and visiting opportunities.
