English bio

ZarateP-04_1_2I am an international law expert. I pursued my first degree in law and social sciences at the University of Chile (class valedictorian), and then specialized in International Law at the Universities of Cambridge (LLM) and Oxford (doctoral studies) in the UK. Within international law, I specialize in dispute settlement, particularly inter-state disputes.

As a practitioner, I have worked for several years for leading international law firms in the UK, France, the US and Switzerland. My experience includes six cases before the International Court of Justice: Costa Rica v Nicaragua (I), as research assistant to Prof. James Crawford at Matrix Chambers (London); Peru v Chile, as associate at Freshfields Bruckhaus Deringer (Paris); and Nicaragua v ColombiaArgentina v Uruguay, Ecuador v Colombia, and Georgia v Russia, as associate at Foley Hoag (Washington DC). I have also been involved in inter-state cases before other international tribunals, and advised numerous governments in non-contentious matters involving a wide range of international law issues, including treaty interpretation, boundary delimitation, the law of the sea, jurisdiction and immunities, economic sanctions, transboundary resources, international criminal law and human rights.

EncuentrosMUI am also experienced in international investment law. In this type of disputes I have intervened as adviser to States as well as to foreign investors. I have also been Administrative Secretary or main assistant to international tribunals in arbitral proceedings held under the auspices of the World Bank (ICSID), the London Court of International Arbitration, the International Chamber of Commerce, the United Nations Commission on International Trade Law (UNCITRAL), and the Energy Charter Treaty.

In parallel with my legal practice, I have also developed a career as a columnist and analyst, and thereby gained a substantial media presence (more information, here).

I am based in Oxford, England, for family reasons (my husband is a Lecturer in International Law at the University of Oxford), where I work as an independent consultant.
