Jayson Maurice Porter is a PhD candidate of Mexican environmental history who also teaches about tropical histories of science and technology studies, material culture, and black geographies. His dissertation research focuses on pesticide-based eradication campaigns—against people, plants, and people—in the Mexican states of Guerrero and Sinaloa. His dissertation will analyze pesticide use across military, public health, and agricultural campaigns from 1920 to 1980 to better understand how ecological, political, and social violence intertwined in two of Mexico’s most violent states.
