Her area of research is public international law (PIL), and her main research lines are related to the points where international environmental law, international human rights law, World Trade Organization (WTO) law and international investment law interact. 

A first research line investigates how the fragmentation of international law into different regulatory and institutional frameworks affects how legislation is created and applied. The fact is that situations of tension between states can generally be assessed from various perspectives: depending on the position adopted, the same situation can be considered a human rights, environmental, or international economic law case. The problem arises when each area provides a different solution to the problem, because it prioritizes different interests. Some international frameworks may become hegemonic over others in these cases.

A second line of research adopts a theoretical and practical perspective in order to investigate how the jurisprudence of human rights bodies deals with certain traditional assumptions of international law. For example, a nascent line of jurisprudence is seeking to redefine and expand the concept of the State's extraterritorial jurisdiction. This expansion aims to broaden states' responsibility with regard to extraterritorial violations of human rights beyond the pre-established propositions.
