Her research interests lie at the intersection of EU law and constitutional law. Her main lines of research include:

• The plurality of systems of rights protection in Europe and the interactions among the Court of Justice of the European Union, the European Court of Human Rights, and constitutional courts
• European constitutionalism and the impact of economic governance
• Rule of law and judicial independence in the EU
• The independence of international courts

Since 2011, she is an external legal expert of the Centre for Judicial Cooperation at the EUI (Florence) and has participated in several projects funded by the European Commission as the UPF coordinator. She is the IP of a project funded by the Spanish government (2018-2021) on “Economic and social constitutionalism: new challenges for the Rule of Law in the EU”, which builds upon a previous research project on the constitutional impact of European economic governance.

She is developing a project on the independence of the international judiciary funded by ICREA Acadèmia. The increasing influence and power of international courts has raised concern regarding their legitimacy, which is premised to a large extent upon their independence. The diverse and partial approaches in examining specific courts hinders a meaningful understanding of what judicial independence means and requires in the international sphere. Her main goal is to provide an analytical framework to conceptualize judicial independence at the international level from which to assess, critically examine, and guide institutional design and practice.
