Max Liboiron is a feminist environmental scientist, science and technology studies (STS) scholar, and activist. As an Assistant Professor in Geography at Memorial University of Newfoundland, Liboiron directs Civic Laboratory for Environmental Action Research (CLEAR), a feminist, anti-colonial laboratory that specializes in grassroots environmental monitoring of marine plastic pollution. Liboiron’s STS work focuses on how invisible yet harmful emerging phenomena such as toxicants from marine plastics become apparent in science and activism, and how these methods of representation relate to action. Liboiron also runs Discard Studies, an interdisciplinary hub for research on waste and wasting. An in-progress manuscript builds on this related work to articulate pollution as a form of colonialism.
