This workshop seeks to create the first interdisciplinary network of researchers studying the technologies and impacts of everyday bordering and deportations in the hostile environment. Investigating the ways in which data and technology is used to create everyday bordering and deportations requires collaboration between data scientists, historians, criminologists and sociologists, and activists. Scholars have written extensively about the exclusionary effect of everyday bordering amid narratives of a hostile environment in Britain, yet there has been a lack in examination of, first, how technology is exerted by the state to reproduce bias and exclusion at borders and, second, and how technology can be used to reduce bias and increase state transparency and accountability.
