Academic background

LLB (UFPE), MJur (Oxon), DPhil (Oxon)

Before joining Jesus College, I was a Postdoctoral Research Fellow with the Oxford Institute for Ethics, Law and Armed Conflict (ELAC), a research programme based at the Blavatnik School of Government. There, I was involved in the Cyber Due Diligence Project, sponsored by the Government of Japan, the Oxford Process on International Law Protections in Cyberspace, in partnership with Microsoft, and Connecting Atrocity Prevention Research and Policy, supported by the UK Research and Innovation Council.

Since 2019, I have taught Criminal Law for Law Undergraduates at St Catherine’s College, Oxford, where I was also a Junior Research Fellow in 2020-2021. I also teach on the Blavatnik School’s Master of Public Policy (MPP) programme. In October 2019, I was appointed Fellow of the UK Higher Education Academy (FHEA).

I completed a DPhil in Law the University of Oxford in 2019. My thesis, entitled ‘Retroactive Recharacterisation of Crimes and the Principles of Legality and Fair Labelling in International Criminal Law’, was awarded a Special Mention of the English-Speaking René Cassin – International Institute of Human Rights 2020 Thesis Prize. Some of the findings of my research were published in the Journal of International Criminal Justice, the International Criminal Law Review, the Journal of Conflict and Security Law and the Human Rights Law Review. My article ‘The retroactive application of the Rome Statute in cases of Security Council referrals and ad hoc declarations: an appraisal of the existing solutions to an under-discussed problem’ was also the recipient of the 2018 Journal of International Criminal Justice prize. My DPhil was supervised by Professor Dapo Akande and generously funded by the Planethood Foundation and the Law Faculty’s Sir Roy Goode Scholarship and Graduate Assistant Fund.

Before starting my DPhil, I interned at the ICC, having been assigned to work with Judge Olga Herrera Carbuccia in Trial Chambers III and V. The internship was funded by the Oxford Global Justice Internship Programme and the Planethood Foundation.

In 2015, I obtained a Magister Juris (MJur) degree from the University of Oxford with Distinction. I was awarded the Clifford Chance Prize for Best Overall Performance in the MJur, the Law Faculty Prize for Best Exam Paper in International Law and Armed Conflict, as well as the Principal’s Prize and Archibald Jackson Prize for Academic Excellence, both awarded by Somerville College. My MJur Dissertation looked at the extent of prosecutorial discretion in international criminal law, particularly with regards to peace and security considerations and alternative justice mechanisms. It has led to the article “‘Interests of justice’: Defining the scope of Prosecutorial discretion in Article 53 (1)(c) and 2(c) of the Rome Statute of the International Criminal Court”, published in the Leiden Journal of International Law in 2017.

I am also a qualified lawyer in Brazil, where I  worked as a Law Clerk in Criminal Law for a High Court Judge for two years. I completed my undergraduate studies in Law (LLB) at the Federal University of Pernambuco (UFPE, Brazil) with a year abroad in France, where I attended Sciences Po-Lille and Université Pierre-Mendès in Grenoble. I graduated with a First-Class Honours degree at the top of my class.
