Pedro A. Villarreal (PhD, National Autonomous University of Mexico) is currently a Research Fellow at the Max Planck Institute for Comparative Public Law and International Law in Heidelberg, Germany. His research interests include the intersection between public health and legal issues, particularly from an international and comparative perspective. The idea of authority as a possible answer to the limits of legal reasoning is of particular relevance for such purpose.

His work has focused on the legal analysis of mechanisms related to pandemic preparedness and response through a global governance approach. This includes addressing the boundaries between legal validity and scientific knowledge. His research also touches upon human rights perspectives, insofar as they can operate as a link between the legal and scientific fields, as it embeds criteria of technical necessity in decision-making processes.
