Marina Walker Guevara

Marina Walker Guevara is executive editor at the Pulitzer Center. Before she was deputy director at the International Consortium of Investigative Journalists (ICIJ), where she managed the two largest collaborations of reporters in journalism history: The Panama Papers and the Paradise Papers. 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. In 2018-2019, she was a John S. Knight fellow at Stanford University where she focused on the use of artificial intelligence in big data journalistic investigations.
