Parastou’s research sits at the intersection of urban and political geography, critical security studies, and international relations. Currently, she looks at the geopolitical dimensions of urban policies of security and development in Western metropolitan centres. Parastou has done extensive research on area-based policies of social development, housing and policing, along with the rise on hard-Right populism in Toronto, Canada. She has also done work on the relational formation of urbanism and colonial pacification in the late 19th and early 20th centuries in French colonies in North Africa. Her current research examines the relations between urban and security policies in the contexts of the United Kingdom and Belgium, as well as at the EU level. In engaging with the multi-scalar dimensions of development and security politics that have deeply shaped the reality of our urban present, her work is invested in envisioning urban policy as a democratic tool of citizenship, one that is essential for a cosmopolitan urban future.
