Joseph's research and teaching are principally oriented by issues of social justice. He deploys critical and cultural theories in order to examine and address the relationship between knowledge and power, issues concerned with discrimination and injustice, state violence, institutional racism, and regimes of colonialism and empire. He examines these issues in the context of everyday cultural practices, the state, institutions of power such as law, and the interface of bodies and technologies.
His most recent publications include two monographs:
State Violence and the Execution of Law: Biopolitical Caesurae of Torture, Black Sites, Drones (Abingdon and New York: Routledge, 2013). The book was nominated for the following international book prizes: the UK's Hart Socio-Legal Book Prize 2014 and the US Law and Society Herbert Jacob Book Prize 2014.
Joseph's key areas of research include: race, ethnicity, whiteness; bodies, technologies; cultural studies of law; migration, diaspora, refugees; and state violence.
