Martha Guerrero Ble is an Advocate at Refugees International, where she leads the organization’s Labor Market Access Initiative—a multi-country effort to expand economic inclusion for displaced populations and advance systemic reform in how governments and international institutions respond to forced displacement.
Her work has contributed to landmark policy outcomes, including Colombia’s mass regularization framework for 1.8 million displaced Venezuelans, the defense of asylum seekers’ right to work in Costa Rica, and the evolution of multilateral development bank financing strategies that have mobilized over $2.2 billion for refugee response globally. She serves as Refugees International’s primary interlocutor with the World Bank, IDB, and other multilateral institutions on displacement financing and labor integration policy. She also champions RLO participation in World Bank financing processes and displacement policy design at the highest levels.
Martha is a widely published researcher and policy analyst. She has authored multiple reports and policy briefs and contributed opinion and analysis to Forced Migration Review, Context Newsroom, Devex, The Hill, and other outlets. She has been interviewed by international media on refugee labor market policy and displacement financing, and has presented her research in high-level convenings alongside World Bank, IDB, and UNHCR leadership.
Prior to her current role, Martha interned with the International Organization for Migration in Myanmar and worked with the Organization of American States on digital inclusion and connectivity across Latin America. She holds an M.Sc. in Foreign Service from Georgetown University and a B.A. in International Business from Tecnológico de Monterrey. She is a native Spanish speaker, fluent in English, advanced in French, and has field experience across Latin America and Southeast Asia.
