  • Research Interests: political ecology, data science, agrarian studies, race, financialization of land






I am interested in the turn towards Big Data science in agricultural research and its implications for climate change, peasant livelihoods, and agroecological landscapes. I explore how agricultural data science reproduces particular forms of standardization and homogeneity that constitute racialized and exclusionary forms of international development and environmental management across the global South, focused on agrarian frontier zones in Colombia. In Colombia, I work with the La Via Campesina popular education school, IALA Maria Cano, as well as several agroecological research teams and am deeply guided and inspired by how these groups combine ecological practice, radical pedagogy, and emancipatory politics in their daily practices and theoretical work.
