I am a historian of transnational science focusing on scientific conceptions of race, culture, and indigeneity in the twentieth century. Through multi-sited and transnational perspectives my work investigates how scientific articulations of human diversity have been used to both legitimize and confront political formations in the modern world.

My first book The Remnants of Race Science: UNESCO and Economic Development in the Global South traces the influence of ideas from the Global South on UNESCO’s race campaign, illuminating its relationship to notions of modernization and economic development. 

Research Interests

Global histories of race science, anti-racism in science, postcolonial studies of science, indigeneity and science, history of international development, history of the human sciences, history of food and nutrition, Latin American history
