Marina Walker Guevara

Marina Walker Guevara is executive editor at the Pulitzer Center, an organization that supports underreported stories worldwide. Before, she was deputy director at the International Consortium of Investigative Journalists (ICIJ). She managed two of the largest collaborations of reporters in journalism history: The Panama Papers and the Paradise Papers, which involved hundreds of journalists using technology to unravel stories of public interest from terabytes of leaked financial data.

Walker Guevara was instrumental in developing ICIJ’s model of large-scale media collaboration, persuading reporters who used to compete with one another instead to work together, share resources and amplify their reach and impact.

Her work as a journalist started in her native Argentina. Her stories on topics ranging from environmental degradation by multinational companies to the global offshore economy have appeared in leading international media, including The Washington Post, Miami Herald, Mother Jones, Le Monde, and the BBC.
