Carlos Santana is an Assistant Professor in the Department of Philosophy at the University of Utah. His work blends empirically-informed philosophy of science with environmental ethics, examining how values are represented in the concepts and methods of the environmental sciences, as well as how those sciences interface with public policy. This has included, to give a couple of examples, critically examining how conservation biologists define and measure biodiversity, and how geoscientists and others are tackling the questions raised by the proposal that we now live in the Anthropocene epoch. This sort of work requires spending a lot of time hanging around scientists, and through conversation and collaboration with researchers at the University of Utah, Carlos has become interested in topics surrounding urban ecology, including the role concepts like “invasive species” should (and shouldn’t) play in planning and managing urban environments, and whether “novel ecosystem” thinking should supplant the traditional values of restoration ecology in cities. Carlos regularly teaches undergraduate courses in environmental ethics, and a rotating set of graduate-level courses on science, environment, and values, on topics such as food, biodiversity, and the philosophy of biology.
