My scholarship focuses on South-South political and social movements, meaning movements shared by marginalized groups across national, linguistic, and racial lines. My first book studied a political movement called the Tricontinental, an alliance of activists from Africa, Asia, and the Americas that began in Havana in 1966. The Tricontinental produced films, posters, and magazines in English, Spanish, French, and Arabic for over fifty years, and it played a key role in shaping our political imagination. I’ve since published on similar topics, including a second book on communist activism in the Global South, and I am a frequent speaker and contributor to magazines and periodicals. Currently, I’m working on a book about one of the most significant solidarity movements of the twentieth century, which was based in Mexico City in the 1920s. I am enthusiastic to teach an engagements course on “Solidarity Beyond the Hashtag,” and I hope my classroom will be a space of experimentation for students to learn how to analyze problems and reflect on difference.
