My research focuses on migration and health in the Americas. At UBC, I teach courses on global history, migration, and Latin America.

My newest book Grounds for Exclusion: Race, Health, and Disability in Argentina, 1876-1932 (UNC Press, 2026) challenges scholars and Argentine society to rethink one of the most dominant and incorrect parts of historical writing and popular memory. Between 1876 and 1932, Argentina excluded with open doors. Over these six decades, state officials developed a long list of grounds for exclusion, which were all reasons that deterred people from ever boarding a ship and that led to the denial of entry to many who tried to come. The widespread inclusion of millions of immigrants in Argentine society in the late nineteenth and early twentieth centuries was predicated on the exclusion of others on the basis of race, health, and disability.
