Gustavo Valdivia is a third-year PhD student at the Department of Anthropology at Johns Hopkins University in Baltimore, Maryland. He is interested in exploring the production of knowledge on climate in, and about, the Peruvian Andes. In his thesis he plans to investigate the intellectual history of the representation of the Andes mountains in climate science, and explore ethnographically the local understandings of climate and climate change in the Andean community of Phinaya. This is an indigenous herding community in Cuzco, where the Quelccaya, the largest tropical glacier in the world, is located. Before starting his PhD at Johns Hopkins, Gustavo received a Master’s degree in climate in society from Columbia University in New York.
