Giacomo Tagiuri is an assistant professor of EU Law at the University of Amsterdam Law School. Giacomo specializes in EU economic law, including internal market, competition and consumer law, which he teaches and researches from an interdisciplinary perspective; drawing on sociology, political economy, and history to understand doctrinal developments in the law. Since March 2025, Giacomo acts as Director of the Amsterdam Centre for European Law and Governance (ACELG). He is also a member of the SGEL (Sustainable Global Economic Law) project.

Prior to joining Amsterdam Law School in September 2021, Giacomo held postdoctoral positions at New York University (Emile Noël Fellow), the European University Institute (Max Weber Programme), and the Safra Center for Ethics at Tel Aviv University. His PhD in Legal Studies from Bocconi University in Milan (2018) followed degrees from the Johns Hopkins’ School of Advanced International Studies (SAIS) (European Studies) and the University of Bologna (Law).

Giacomo’s research project for the years 2023-2029 is funded by an UVA starters grant and is titled “Regulating European Economic Lives: Culture, Markets, and the Law”. Within this project Giacomo is completing a monograph by the same title exploring the effects of EU economic law on culturally valued market arrangements in the member states. Through in depth case studies (retail entry regulation; resale price maintenance in books markets; and selective distribution) he describes interactions between local market arrangements and EU law and how said interactions shape the 'economiv lives' of Europeans - a concept developed by economic sociologists which captures the interconnectedness of market experiences, social relations and personal identities. 

More broadly, Giacomo’s work conceptualizes how EU law shapes and transforms markets and society (Transnational Legal Theory), with a particular attention to the EU regulation of the digital economy (Yearbook of European Law; Repositioning Platforms in Digital Markets Law) and other proecesses of market transformation. Giacomo's research answers questions about the type of interests and concerns that drive market regulation (Columbia Journal of European Law), as well as more normative and socio-theoretical questions around the justifications for specific types of market regulation (Cambridge Handbook of Algorithmic Price Personalization and the Law), and how to make markets more democratic (European Journal of International Law; European Law Open) 

Giacomo presented his research at various institutions in Europe and the US including the European University Institute, Sciences Po, IE University, the Max Planck Institute for Comparative Public Law and International Law at Heidelberg,  New York University, Yale Law School, and the University of Michigan.

Giacomo's teaching spans various areas of EU Law. At the bachelor level, he teaches the course “Power, Politics, and Values in EU Law” part of the minor in 'EU Law and Politics' which Giacomo coordinates. At the master level he coordinates and teaches in the course “European Competition Law” - the defining mandatory course in the European Competition Law and Regulation master track. Giacomo supervises master and phd theses in various areas of EU law and market regulation.
