I am a Mexican lawyer with an LLB from ITAM's Law School (2019) and an LLM in International Law from Cambridge (2022). My research examines how judicial doctrines influence the agency of states in shaping international human rights law. I approach this overarching inquiry from three frontlines—constitutional, international, and transnational law. At the constitutional level, I analyse the global governance implications of the interpretative approaches adopted by national courts toward international law. At the international level, I study how doctrines of review employed by international tribunals restrict the capacity of national courts to shape the meaning and scope of international law. At the transnational level, I examine how doctrines of extraterritorial jurisdiction enable states to project their domestic rules into the international arena. The aim of this research is to identify who holds authority in defining international human rights law, and to explore how this process might be made more democratic.
