Marco Vallejos (he/him, diasporic settler of color) is a joint graduate student at UW-Madison in the Department of Geography and Nelson Institute for Environmental Studies researching plastic movement in fluvial and lacustrine landscapes. Using transdisciplinary methodologies between geomorphology and waste theory, I aim to (dis)entangle the societal and geologic aspects of environmental plastic from micro to macro scales, applying an environmental justice lens when applicable. I ground my research and way of being in anti-colonial, feminist, and BIPOC scholarship and community. Growing up in south Florida, I completed my BA in Geosciences from Williams College with a concentration in Science and Technology Studies (STS). When not in old academic buildings, I enjoy playing volleyball, fishing, and coaxing a perfect shot of espresso from a finicky machine.
