Troy Vettese

Find our Sentientist Conversation here on the Sentientism YouTube and here on the Sentientism podcast.

Troy Vettese is an environmental historian who specializes in environmental economics, animal studies, and energy history. In 2019 he completed his doctorate in history at New York University. From 2019 to 2021, he worked at Harvard University as a William Lyon Mackenzie King postdoctoral research fellow. He has collaborated with Drew Pendergrass, an environmental engineer, on numerous projects including their book Half-Earth Socialism: A Plan to Save the Future from Extinction, Climate Change and Pandemics .

Troy is currently revising his dissertation on neoliberal environmental thought into a book, tentatively titled ‘Beyond Externality’. In addition to his academic work, Vettese writes on a wide array of environmental topics for a popular audience, and has had essays published in the Guardian, the New Statesman, Jacobin, N+1, Book Forum, and Boston Review.

Troy has a broadly naturalistic worldview. He is vegan and has, at least, a sentiocentric moral scope.
