Marina Walker Guevara

Director of Strategic Initiatives , ICIJ

Marina Walker Guevara is 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 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).

We gather today amid a growing global backlash against human rights, democracy, and an independent press. Even in countries where we thought our colleagues were relatively secure, the news media is under serious assault. At the same time, we face a business model that has all but disappeared, technology that seems to change not yearly but daily, and issues that threaten not only our profession but the Earth itself. 

And yet... In many ways investigative journalism is stronger than ever. An investigative press has spread worldwide, and those who believe in social accountability and progress now recognize that watchdog reporting is as essential to development as good healthcare, honest cops and a level playing field for business. 

With this in mind, we start GIJC19 with a look forward. Here are six big thinkers from six countries, with expertise ranging from kleptocracies to artificial intelligence, to give us a glimpse at the challenges ahead.

Editing doesn't start when the story lands. Great editing starts at story conception and continues through the reporting process, all the way to final project. As investigations become increasingly complex and include multiple technologies, online search and verification, as well as multiple reporters, sometimes across cultures, countries and time zones, getting the team organized and on track requires project management skills as well as the nitty gritty of storytelling, fact-checking and verification as well legal concerns around bullet-proofing your story. Our panel will discuss how they get the best out of their reporting and their stories, including tips and tools to how they get their work done.
