Zachary Elkins is Professor in the Department of Government at the University of Texas. He publishes widely in the fields of comparative politics, methodology, and public law, with a focus on Latin America and the origins and consequences of constitutional design. He co-directs the Comparative Constitutions Project and has developed a set of tools to analyze constitutions and other canonical documents.
