Areas of Study: International Economic Law

Mario’s scholarship encompasses international trade, international investment, and international tax, as well as comparative antitrust and competition. His research interests also include international monetary matters, global finance, sovereign debt, global governance, development, and legal theory.

Mario’s dissertation entitled “Is International Economic Law International or Economic (or Law?)” sets out to examine the complex political choices embedded in the law and practice of international economic relations. By drawing on insights from history, sociology, political science, and economics, his doctoral work seeks to challenge the connections between law and historical narrative, political economy, and economic theory that prevail in the field of international economic law today. In doing so, its goal is to bolster a version of legal analysis that situates relations of power at the center of inquiry and carve out a new and unique role for law in ongoing discussions about the normative futures of the world economic order.

Mario is currently a Senior Fellow at Georgetown Law’s Center on Inclusive Trade and Development. While at Georgetown, Mario has also been an Inaugural Fellow at the Center for the Advancement of the Rule of Law in the Americas, a Senior Fellow at the New Markets Lab, a Salzburg Cutler Fellow, and a Fellow at Georgetown Law’s Institute of International Economic Law, as well as a Teaching Assistant for several courses.
