Renzo Taddei teaches anthropology and environmental sciences at the Federal University of São Paulo (UNIFESP). Prior to joining UNIFESP, he taught at the City University of New York and the Federal University of Rio de Janeiro. He served as a visiting professor at Yale, Duke, and the University of the Republic of Uruguay. He has engaged in ethnographic work in Brazil, Argentina, and the United States, mainly on how collectivies interact with the atmosphere—trying to predict its behavior, being impacted by its variations, or purposefully manipulating it. His current research compares the ethics and politics of geoengineering with those of non-Western forms of intervention in the atmosphere (which he calls alter geoengineering), such as the ones found among African-Brazilian religious traditions and in Amazonian varieties of shamanism.
