I am a historian of the Gulf South Frontier, an area stretching northward from the Gulf of Mexico to the Tennessee and Arkansas Rivers, and westward from the Suwannee River in Florida to the Brazos River in Texas. I am particularly interested in the interaction between the region's Native Americans, Europeans, and Africans in the period from between 1650 to 1850, an era during which Spain, France, and Great Britain claimed portions of the area, with ultimately the United States establishing hegemony in the early nineteenth century. In addition to teaching a class on the Gulf South Frontier, I also teach classes on Southern Plains Indian History, the Spanish Frontier in North America, and the French Frontier in North America.
