deputy director, International Consortium of Investigative Journalists, Washington, D.C.
Marina Walker Guevara is the deputy director of the International Consortium of Investigative Journalists (ICIJ). She managed the two largest collaborations of reporters in journalism history: the Panama Papers and the Paradise Papers. Both investigations involved hundreds of journalists using technology to unravel stories of public interest from terabytes of leaked financial data. Before becoming an editor, Walker Guevara investigated environmental degradation by mining companies, cigarette smuggling by leading tobacco firms and the shadowy world of offshore finance. Her story “Children of Lead” revealed a public health crisis in a Peruvian town caused by an American-owned lead smelting company. She has won and shared more than 40 national and international awards, including a Pulitzer Prize for Explanatory Reporting. She earned a master’s degree in journalism from the University of Missouri and also graduated from the Universidad Nacional de Cuyo. She is a native of Mendoza, Argentina.
