Alyne Costa is professor of philosophy at the Pontifical Catholic University of Rio de Janeiro, Brazil. She is also an associate researcher at Association for Researches and Practices in the Humanities (APPH), a self-funded nonprofit research and educational association based in the city of Porto Alegre, and a member of the Age of the Earth Network, which brings together researchers interested in the debate and practice of ecology, in a broad sense. Her research focuses on the philosophical and political implications of the Anthropocene, for which she draws mainly from science and technology studies, multispecies ethnography and amerindian perspectivism. She is currently working on what could be called “ontologies of the Earth”, an attempt to deploy notions such as “world”, “planet” and “earth” in a way which combines ontological pluralism and interdependence. She is also the coordinator of the Earth and Us: Education, Research and Citizenship in the Anthropocene (2022-2024) project, which aims to articulate an international and interdisciplinary network of researchers, artists and activists to gather cognitive, affective and political resources for living in the Anthropocene. The project is also responsible for the production of both Brazilian and Latin American editions of the Anthropocene Campus.
