Research topic

Data Governance, Collective Autonomy, Decolonial Thinking

Sebastián’s doctoral research examines the politics underpinning the governance of large volumes of data from the perspective of collective autonomy put forward by communities in Latin America whose livelihood has been threatened by modernity. In relation to current debates, Sebastián’s proposal calls for decentring the principles of openness and sovereignty and aligns with ongoing work on data colonialism. The thesis draws on the case of astronomy data in Chile, where a broad range of local actors see the informational resources being produced by the international mega observatories constructed in the Atacama Desert as an opportunity for scientific, technological and economic progress. Sebastián’s empirical analysis describes the reconfiguration of discourses and political economies of collaboration, extractivism and indigenous territorial struggles in times of datafication.
