Advisory Board Member

Marina Walker Guevara is executive editor at the Pulitzer Center on Crisis Reporting, a non-profit that partners with journalists and newsrooms to support in-depth reporting on critical global issues. 

For the past 14 years, she held leadership positions at the International Consortium of Investigative Journalists, a network of reporters in 90 countries who work together on stories of global importance. 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 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.

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. Walker Guevara sits in 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).
