Xavier Silva, PhD

Dr. Xavier Silva, who is Ecuadorian, received his PhD in entomology applied to ecology from the Sorbonne in Paris, France. There, he also earned his master’s degree and BS, focusing on ecology and biology, including population ecology, biogeography, and other environmental sciences applied to tropical ecosystems. He has worked extensively in the conservation of natural resources in Latin America and the Caribbean, as well as in several countries in Africa and Asia. For several years, Dr. Silva was director of conservation science for The Nature Conservancy’s Latin America and the Caribbean program based in Washington, DC. He was also director of NatureServe’s Latin America and Caribbean program. He has also taught at the University of San Francisco Quito and has written several books, including Butterflies of Ecuador and Ecuador’s Butterfly Ecology, which was awarded Best Biological Publication of Ecuador in 2012. Dr. Silva has been president of the Entomological Society of Ecuador and a member of the Entomological Society of France and the Ornithological Society of Ecuador.
