Marina Walker Guevara

Marina Walker Guevara, United States, is executive editor at the Pulitzer Center. Prior to that, she was ICIJ’s director of strategic initiatives and network.

She managed the two 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 has been instrumental in developing the science behind 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, where she received the Perfil Freedom of Expression Prize in 2016. 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, The 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 and honors from Long Island University’s George Polk Awards, Investigative Reporters and Editors, Overseas Press Club, Bartlett and Steele Awards, Columbia University’s Maria Moors Cabot Award for distinguished Latin American reporting (special citation) and the inaugural Susan Talalay Award for Outstanding Journalism.

In 2018-2019, Walker Guevara was a John S. Knight Fellow at Stanford University where she studied the use of artificial intelligence in big data investigations. That same year, she received the Missouri Honor Medal for Distinguished Service from her alma mater, the Missouri School of Journalism.

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 Reporting (CLIP).
