Marina Walker

Marina Walker Guevara is executive editor at the Pulitzer Center, an organization that supports in-depth journalism and civic engagement globally. Before joining the Center, Walker Guevara was deputy director of 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 the 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. She has won or shared more than 50 national and international awards, including the 2017 Pulitzer Prize for Explanatory Reporting. In 2018-2019, she was a John S. Knight fellow at Stanford University. During her fellowship, she focused on the use of artificial intelligence in big data journalistic investigations. Walker Guevara sits on the board of directors of the Global Investigative Journalism Network (GIJN) and is a co-founder of the Latin American Center for Investigative Journalism (CLIP).
