Maria is a paralegal in the international protection team, where she provides legal support on multiple complex asylum and international protection claims. She is assisting with a judicial review claim challenging a complex asylum refusal, which has involved gathering expert evidence and bringing technical arguments that are on the cutting edge of international refugee law. She is also assisting on a politically sensitive extradition case out of a foreign jurisdiction, where a team of lawyers from several jurisdictions are instructed, and that involves arguments engaging several provisions under the European Convention on Human Rights.

A foreign qualified lawyer in Argentina, Maria has represented the University of Buenos Aires at the Philip C. Jessup International Law Moot Court Competition, the Nelson Mandela World Human Rights Moot Court Competition and the Jean-Pictet Competition.

Before joining Gherson LLP, she worked at the Argentinean Human Trafficking Prosecutor Office. She was also consultant at the British Institute of International and Comparative Law (BIICL), and a visiting researcher at the Max Planck Institute for Comparative Public Law and International Law. Maria also completed a volunteer placement at the Human Trafficking and Migrant Smuggling section at the UNODC.

Her key interest lies on the interplay between International Refugee Law, International Human Rights law and Public International Law.

Maria graduated as a lawyer from the University of Buenos Aires in 2017, with Honours. She completed an LLM in Human Rights Law at Queen Mary University of London, with Distinction.
