Haylie's research examines spaces of female street-based sex work in the port cities of Hull (UK) and Rotterdam (Netherlands) between the late-Victorian industrial period and the present.  Focusing on these cities for their long-standing geographic, cultural and economic connections, this is a relational study of the interplay between spaces of sex work (the so-called 'red-light district') and the relative but distinct histories of these cities that connect to patterns of urban development as a means to explore the production and reproduction of 'moral space'.
