Lawyer and economist turning legal risk into commercial strategy for international organisations and growth firms.

United Kingdom

Message

I am a lawyer and economist with an LLM from LSE, experienced in translating complex legal risks into commercial decisions across multi-jurisdictional matters, particularly in Latin American markets. I have led high-stakes litigation, regulatory tracking, and cross-functional crisis responses, delivering evidence-based strategic briefings and compliance frameworks for multinational clients.

As a consultant and former associate, I design risk mitigation and governance frameworks, advise on public affairs and regulatory strategy, and teach law and economics. I combine quantitative training in econometrics with practical litigation and stakeholder management experience to provide decision-ready legal and strategic counsel.
