A prolific scholar, Alarie has authored or co-authored seven books and over 65 peer-reviewed articles. His landmark book, The Legal Singularity: How Artificial Intelligence Can Make Law Radically Better (University of Toronto Press, 2023), co-authored with Abdi Aidid, won the PROSE Award from the Association of American Publishers and was shortlisted for the Donner Prize. His research on AI’s impact on tax law, legal theory, and judicial decision-making is widely cited and has influenced both policymakers and industry leaders.
