Voluntary


International Centre for Dispute Resolution (ICDR)
Brazilian Advisory Council (2024)

Advise ICDR on how arbitration is seen and practised in Brazil. The role includes sharing trends and local developments—often things that don’t yet show up in data or doctrine.




Brazilian Arbitration Committee (CBAr)
Regional Coordinator – North (2024–2027)

Represent CBAr before institutions in the North of Brazil. It’s a way to keep arbitration visible and understood in a region familiar to me, but where it is unfamiliar to many.

Cambridge University Arbitration Society (Cuarb)
President (2024-2026), Vice-President (2023), Lectures Chair (2023)

Led the society’s activities with the Lauterpacht Centre, including the Lecture Series and the Cambridge Arbitration Day. I try to make the society a space for both curiosity and rigour.




Gates Cambridge Council
Board Member and Tech Officer (2023–2024)

Manage the IT systems for the Gates community spaces. Most of the work was quiet—making sure things run smoothly, setting up tech for talks and gatherings, and helping others use the space well.



Northern Centre for Arbitration Studies – NEA
Founding Member and Board Manager (2015–2019)

I set up this NGO to connect students and practitioners working with arbitration in the North of Brazil. Coordinated events with guests from other parts of the country and organised the first Arbitration Congress of the North. Supported the creation of arbitration groups in at least seven universities in Manaus, helping build something that could last beyond my own involvement.



Brazilian Association of Students of Arbitration (ABEArb)
National Board Director (2019), Amazonas State Ambassador (2018)

Promoted student engagement in arbitration—especially outside of the usual world centres.




Law Academic Association – Federal University of Amazonas (CAD-UFAM)
Chair of the Fiscal Council (2015), Vice-President (2016)

Organised two major conferences that gathered at least 350 people each. and led student politics. It was early work, but quite important in retrospect.
