Her first book, Tracking Modernity: India, Trains, and the Culture of Mobility (University of Minnesota, 2011), explores cultural representations of modernity by considering how the railway was imagined in colonial, nationalist and postcolonial South Asian contexts. Her second book, Arranging Marriage: Conjugal Agency in the South Asian Diaspora (forthcoming University of Minnesota, 2018), rethinks conjugal narratives and practices as a dynamic part of contemporary globalization. Aguiar teaches regularly on culture and globalization, postcolonial studies, gender studies, transnationalism and diaspora, and Anglophone global literature, especially South Asian literature. She is currently researching a new book on refugee mobilities.
