Abigail Nieves Delgado is an Assistant Professor of History and Philosophy of Science at the Freudenthal Institute at Utrecht University. Her research focuses on the use of racial categories in science, the political and anthropological dimensions of postgenomics (especially in epigenetics and microbiome research) as well as on the history of symbiosis and holobiont research. Other research interests are history of biometric technologies and the concept of bias, colonialism in science and technology and epistemic pluralism in ethnobiology. Two of her recent publications on the use of race in scientific practice are: “Does the human microbiome tell us something about race?” published in Nature: Humanities and Social Sciences Communications (2021) and “The face of the Mexican: Race, nation and criminal identification in Mexico” published in American Anthropologist (2020).
