He advises clients on existing and tailored-made options to fund their cases, as part of the Global International Arbitration team. His sophisticated understanding of international investment and international commercial arbitration comes from working in various capacities in international arbitration, including as counsel for private parties and sovereign clients, arbitrator in international and domestic arbitrations, lead negotiator of investment treaties, and ICSID Counsel.
As a practitioner, he concentrated his practice in international investment arbitration and public international law, representing sovereign States and private parties before the International Centre for Settlement of Investment Disputes (ICSID) and the International Chamber of Commerce.

He is former Foreign Investment Director of the Ministry of Trade of Colombia where he conducted a program to strengthen the State’s readiness in case of investor-State arbitration and headed the drafting and updating of the Colombian International Investment Agreement (IIA) Model. Based on this Model, he successfully concluded over twelve IIA negotiations with States from Latin America, North America, Europe and Asia which included bilateral investment treaties and investment chapters of free trade agreements (FTAs). In his former capacity he also led negotiations for Colombia of cross border trade in services and telecommunications chapters of several FTAs. Professor Rivas is former Counsel of ICSID and has substantial experience on ICSID and UNCITRAL rules of arbitration.
