Career Biography

I am a legal executive with over 25 years of experience in the oil and gas industry, having developed my career in leading international companies such as Maxus Energy, YPF Empresa Petrolera Andina, and Repsol Bolivia I currently serve as general counsel of one of Bolivia’s leading energy companies, where I advise on strategic matters and support executive decision-making across the entire value chain.

My experience focuses on regulatory affairs and government relations, with active participation in public-private dialogue and in initiatives related to sectoral policy development. I have also held institutional leadership roles, including vice president of the Bolivian Hydrocarbons Chamber and board member of the Santa Cruz Chamber of Industry and Commerce.

In the field of international relations, I served as head of mission of the Plurinational State of Bolivia to Brazil, representing the country in a strategic posting and contributing to the strengthening of bilateral relations. I participated in high-level and ministerial discussions linked to the process that led to the execution of the Eighth Addendum to the Gas Supply Agreement (GSA) with Brazil.

I approach my work with a strong commitment to professional integrity, sound judgement, and results in complex and high-stakes environments.

How do you approach managing legal aspects during periods of instability or crisis to ensure the organisation’s resilience?

Artificial intelligence is no longer a speculative prospect for in-house legal departments; it is a practical reality that is reshaping how we deliver legal services. At Repsol Bolivia, we have begun incorporating AI-driven tools into our workflows, particularly in contract analysis, regulatory research, and document management. These tools allow our team to process large volumes of documentation with greater speed and accuracy, freeing our lawyers to focus on higher-value strategic advisory work.

That said, we approach AI adoption with a measure of prudence that I consider essential for any general counsel. The deployment of AI in a legal department must be accompanied by rigorous data protection protocols, especially in a jurisdiction such as Bolivia where the regulatory framework governing data privacy continues to evolve. We ensure that any AI tools we utilise comply with applicable Bolivian legislation and with Repsol’s global data governance standards.

Looking ahead, I am convinced that AI will fundamentally alter the composition and competencies of in-house legal teams. Lawyers will increasingly need to develop technological literacy alongside their traditional legal skills. The general counsel’s role will be to guide that transformation responsibly—ensuring that technological innovation serves, rather than undermines, the core principles of sound legal judgement, confidentiality, and professional ethics.
