He has also been a Visiting Professor of Law at Yale University, the School of Advanced Studies in the Social Sciences in Paris, the University of Rome III, and the University of Paris X-Nanterre, and a Visiting Professor of Philosophy at Oxford University, University College London, and University of California, San Diego.

His teaching and research interests are in moral, political, and legal philosophy, in both the Anglophone and Continental European traditions, and the law of evidence. His authored books include Nietzsche on Morality (Routledge, 2002; 2nd ed., 2015), Naturalizing Jurisprudence (Oxford, 2007), Why Tolerate Religion? (Princeton, 2013), Moral Psychology with Nietzsche (Oxford, 2019), Teoría del Derecho realista. Ensayos selectos (Zela, 2024), and (with Jaime Edwards), Marx (Routledge, 2025). He is currently finishing a book exploring realism in political and legal theory, From a Realist Point of View, for Oxford University Press. His work has been translated into French, Italian, Chinese, Russian, Portuguese, Spanish, Japanese, Hebrew, Turkish, Polish, Slovak, and Greek.

Leiter has delivered major lectures around the world, including the Paolo Bozzi Prize Address at the University of Turin, the Julius Stone Address in Jurisprudence at the University of Sydney, the Fresco Lectures in Jurisprudence at the University of Genoa (twice), the Taylor Lecture in Philosophy at the University of Otago, the ‘Or ‘Emet Lecture at York University, Toronto, the “Headliner” address at the annual Legal Theory Symposium at the National University of Singapore, and the opening plenary address at the 30th biennial World Congress of Legal and Social Philosophy in Bucharest. He is founding editor of the Routledge Philosophers book series and (with Leslie Green) of Oxford Studies in Philosophy of Law. He also serves on the editorial boards of Legal Theory (of which he was editor from 2000-2008), Notre Dame Philosophical Reviews, Journal of Nietzsche Studies, Journal of Moral Philosophy, The Philosopher’s Annual, Anilisi e Diritto (Italy), Problema: Anuario de Filosofia y Teoría (Mexico), Indian Journal of Legal Theory, Belgrade Law Review (Serbia), Revista de Teoría Jurídica (Argentina), Revista Estudos Institucionais (Brazil), and Revista Jurídica Facultad de Jurisprudencia (Ecuador), among others.
