Borders have become a key site and central concern of global security practices and theory, from the Mexican-United States border to the Mediterranean ports of the EU. The many facets of borders are introduced and analysed in this programme: they are understood as containers of identity, sites of power, and points of weakness where the mobility of people (eg terrorists, migrants) and things (eg drugs, weapons) can disrupt prevailing forms of security. This programme aims to help students navigate this complex terrain by providing a firm grounding in critical border studies, offering the chance to apply their academic insights within a work-based environment with borders/security professionals through the Borders Internship module.
