Kaysha Corinealdi is an Assistant Professor of History at Emerson College and a historian of imperialism, migration, citizenship, and activism in the twentieth century Americas. As an ALARI Fellow she will complete revision work for her book manuscript Defining Panama: Zones of Exclusion and Afro-Caribbean Diasporic World Making, under contract with Duke University Press. Defining Panama examines how Afro-Caribbean Panamanians, the descendants of the Panama Canal builders, and the targets of multiple national and imperial exclusionist campaigns throughout the twentieth century, used their work as journalists, educators, labor unionists, civic organizational leaders, public intellectuals and cultural producers to challenge discrimination, xenophobia and denationalization. The book traces this activist work as it grows in late 1920s Panama, traverses the anti-communism discourse engulfing the mid-twentieth century Americas, and further transforms in late 1960s Civil Rights New York. Corinealdi has received research support from the Woodrow Wilson National Foundation and her work has also appeared in the Caribbean Review of Gender Studies, the International Journal of Africana Studies, the Hispanic American Historical Review and the Global South.
