I am a PhD student in the French section of MMLL and a member of Queens' College. My research examines the material infrastructure of Paris in the late eighteenth century as it relates to the imagination of the city. My project probes the issue of a series of sinkholes in Paris during the last half of the eighteenth century as a focal point in the changing material and imaginary nature of the city. I explore the relationship between the material and imaginary of the city with mobility of migrant workers and tourists in early modern France.
