Rachel Cypher is an anthropologist and writer. Her work investigates how people make worlds under conditions of environmental crisis and rupture.

Her first book draws on long-term ethnographic fieldwork in Argentina's Pampas to examine how genetically modified crops reshape everyday life. It argues that even one of the world's most standardized commodity supply chains depends upon inherited obligations, informal economies, and enduring attachments to land, family, and place.

Cypher is co-editor, with Nils Bubandt and Astrid Oberborbeck-Andersen, of Rubber Boots Methods for the Anthropocene: Doing Fieldwork in Multispecies Worlds (UMP 2023).

As a Fulbright Scholar in Argentina and as a Postdoctoral Fellow and Research Scholar at the University of Pennsylvania (2022–2025), Cypher conducted collaborative research on climate adaptation and water futures in the Americas.

She is originally from Tucson, Arizona.
