I am inclined to see international law as an inescapable part of the richness and fluidity of the world we live in. Alongside my teaching and research at the University of Lodz, I enjoy engaging with international law across different regions, intellectual traditions, and academic cultures, and exploring how these different perspectives can illuminate what the discipline tends to take for granted.
