Juan Tello Mendoza is a lecturer of Constitutional Law at the University of Barcelona, and a member of the Study Group on Democracy and Constitutionalism at the University of Barcelona. His doctoral dissertation critically explored the "conventionality control" as a doctrine created and used by the Inter-American Court of Human Rights. While at Princeton, he will focus on the Rule of Law and the determination of fundamental rights to explore which branch (judicial or legislative) must have the pre-eminence of that duty. 

Juan holds a PhD in Constitutional Law from the University of Barcelona, an LLM in Human Rights from the University of Navarra, and an LLB from the Pontifical Catholic University of Peru.
