Personal profile

Personal profile

I am a historian of the United States with an emphasis on imperialism, race, gender, and sexuality. Trained in U.S. and Japanese institutions, I have always taken comparative and transnational approaches in my study of history. 

Research Interests

U.S. continental and overseas expansion; women, gender, and sexuality; U.S. and Atlantic/Pacific world; African American history     

Professional Information

I am currently working on two projects: tracing the origins of U.S. imperial engagements in Pacific islands and their racial, sexual, and labor aspects, and investigating the impact of U.S. expansion into East Asia on the domestic formation of Blackness and gender and on the development of Japanese racial identity. 

My first book, Tropical Freedom: Climate, Settler Colonialism, and Black Exclusion in the Age of Emancipation (Duke, 2017), argues that during the late eighteenth and mid nineteenth centuries British and American expansionists and free Black activists produced different imaginings of an Atlantic world that variously and often contrastingly mapped Black freedom within its geographic bounds and that these conflicting geographies of race and freedom became inseparably intertwined with U.S. and British North American settler colonial formations.  Importantly, both promoters and protesters of geographic management of race employed tropes of domesticity and intra-racial reproduction as well as climatic idioms born of the centuries-long development of the plantation economies in the Americas. 

I have also published articles on fugitive slave narratives, women's antislavery activism, and self-emancipated people in Canada, all set in transatlantic settings, and on the intersectional articulations of race, gender, and class among white and American Americans in the context of U.S. expansion into Japan.
