Professor González-Rivera’s legal scholarship currently centers on three main ongoing projects. First, the development of an originalist theory of constitutional interpretation that incorporates and operationalizes Policy-Oriented Jurisprudence (the works of Myres McDougal, Harold Lasswell, and Michael Reisman) in our domestic adjudication process, centered around the concepts of human dignity, freedom, and flourishing. Second, a theory and empirical account of federal police powers, especially in the case of emergencies or so-called “states of exception,” to better analyze and appraise judicial review of emergency Covid-19 measures during the last 4 years. And third, a theory and account of the intersection of our constitutional law and international law and human rights commitments.
Professor González-Rivera has been recently awarded a fellowship as a Visiting Scholar at Georgetown Law’s Center for the Constitution, where he will conduct and present some of his research and writing on federal emergency police powers this Fall 2024.
