Archaeologist and National Geographic grantee Francisco Estrada-Belli pioneered the use of satellite-based technology to locate archaeological sites. His recent research in northern Guatemala has resulted in the discovery of several sites including the lost city of Cival, one of the earliest centers in the Maya lowlands. He is currently an Adjunct Professor at Tulane University, and previously taught archaeology and remote sensing at Harvard University and Vanderbilt University. He is also a member of the Facultad de Humanidades of Universidad San Carlos Guatemala, a Fellow of the Society of Antiquaries of London, and a Research Associate of the American Museum of Natural History. In 2010 he founded the Maya Archaeology Initiative, a non-profit organization dedicated to preserving Maya heritage through archaeology and education in Guatemalan schools. He continues to conduct yearly mapping and excavation campaigns in northern Guatemala.
