Her current book project, Law’s Borderlands: Life, Liberty, and Property in an Old American South, is a legal history of the Florida borderlands during the revolutionary era. Her work reconstructs the complex legal world of the Florida borderlands to show how four legalities–Indigenous, Spanish, Africana, and Anglo–constituted a cosmopolitan legal order in this contested region at the turn of the nineteenth century. During the repeated upheavals of this period, cross-cultural law and justice served as a tool that many Indigenous people, Spaniards, people of African descent, and Anglo-Americans used, intentionally and unintentionally, to control local violence and stabilize their relationships in mutual opposition to the growth of the United States. Disputes over land, slaves, horses, and murder involved dynamic exchanges of legal ideas and practices among Indigenous peoples and immigrants from Europe, the United States, and Africa–all of whom depended on these shared experiences with law to bolster their alliances and block U.S. expansion into East Florida after the American Revolutionary War.
