Marina Walker Guevara is ICIJ’s deputy director. A native of Argentina, she has reported from a half-dozen countries and her investigations have won and shared more than 12 national and international awards. Over a ten-year career, she has written about environmental degradation in Latin America by multinational corporations; shadowy U.S. government HIV/AIDS prevention programs in Africa, and the cigarette mafia in the Tri-Border Area of South America, among other topics. In March 2006 she was awarded the European Commission Lorenzo Natali Prize (Latin America and the Caribbean region) for her reporting about environmental damage caused in Peru by a U.S.-based mining company; that investigation also won her the 2006 Reuters-IUCN Media Award for Excellence in Environmental Reporting.
