José Miguel Nieto Olivar

José Miguel Nieto Olivar is an assistant professor at the School of Public Health of the University of São Paulo (Brazil). He is responsible for courses on Anthropology of Health, Body, and Society, Social Studies of Science, and Research Methodology. Dr. Nieto Olivar was born in Bogotá, Colombia, where he studied Social Communication and obtained his MA in Latin-American Literature. In his home country, he worked with and around human rights, sexual and reproductive rights, and gender in the context of the internal armed conflict. In 2010, he obtained his PhD in Social Anthropology at the Federal University of Rio Grande do Sul, in Brazil. His doctoral dissertation was an ethnography on the political creation and enacting of Brazilian sex workers seen from the perspective of their affective, sexual, marital, and labor trajectories. In 2013, it was published as the book “Devir Puta” [The Wore Becoming].
Between 2010 and 2017, Dr. Nieto Olivar was a researcher at the Center for Gender Studies PAGU, at the State University of Campinas (Brazil), conducting anthropological research with intersectional perspectives about gender, sexuality, money, violence, mobilities, the borderland, and the State. Fieldwork took place in the cities of Tabatinga and São Gabriel da Cachoeira, both situated in the northwestern Brazilian Amazon, in the transborder complex with Peru, Colombia, and Venezuela. Based on the relationships established with the Brazilian movement of sex workers and also with Amazonian border cities, he is currently developing a long-term research project on experimentations of struggle and care in critical contexts, in dialogue with black poetics and feminisms, transfeminisms, putafeminisms, decolonial feminisms, indigenous knowledge, and the discussions on "cosmopolitics" and the "end-of-the-world". This project takes a pluri-epistemological approach that seeks to nurture a creative dialogue in the intersecting spaces between anthropology, public health, and the arts, and serves as a framework for the work that he will develop at CLACS/Brown University in 2023.

At Brown, she is working on two projects: 1) a grant proposal focusing on militarized masculinities among marginalized Latinos in Southern California; 2) a book on the paradoxical interconnectedness of love and violence, expanding the arguments from her 2022 article, “Beyond the Dead Zone: The Meanings of Loving Violence in Highland Mexico” (American Anthropologist). Her research is driven by the desire to humanize misunderstood populations, such as survivors and perpetrators of violenceby uncovering the narratives and structures that shape their circumstances.


Kristen Kolenz - Postdoctoral Fellow, Mellon Sawyer Seminar: Rethinking the Dynamic Interplay of Migration, Race, and Ethnicity in the Caribbean and Latin America (AY 2021-2022)          Email:     kristen_kolenz@brown.edu

Kristen A. Kolenz earned her MA and PhD in women’s, gender, and sexuality studies at The Ohio State University and her BA in philosophy at John Carroll University in Cleveland, Ohio. Her research focuses on resistance to state violence, Central American social movements, migration, and the transformative potential of everyday practices through the lens of decolonial and transnational feminisms. She is currently working on her book manuscript, an analysis of the transnational movements and community-building practices of Central Americans subjected to forced migration, dangerous crossing conditions, and confinement. In the study, Dr. Kolenz takes an interdisciplinary methodological approach that combines ethnographic methods, her own activist practice, and performance studies. The project bridges the fields of Latin American and Latinx Studies, bringing together research conducted in Guatemala, the Sonoran Desert, and immigrant justice movements in the US. The project’s goal is to document the transformative possibilities that emerge from Central Americans’ everyday practices of coping with loss, distance, and violence and to theorize transnational belonging in resistance to white supremacy.
