Biehl has written two books in English: "Vita: Life in a Zone of Social Abandonment" (University of California Press 2005) and "Will to Live: AIDS Therapies and the Politics of Survival" (Princeton University Press 2007). The books are ethnographic studies of the experience and treatment of mental illness and HIV/AIDS, respectively. Both Vita and Will to Live explore new geographies of access and marginalization that have emerged alongside pharmaceutical globalization. They also elaborate on networks of care that poor urban patients create in their daily struggles to survive.
