Biography
I’m a historian of the American West, with a focus on slavery and freedom at the far edges of the nation. My first book, West of Slavery: The Southern Dream of a Transcontinental Empire (UNC Press), won the 2022 Wiley-Silver Prize from the Center for Civil War Research and was a finalist for three other book awards, including the Lincoln Prize. The Civil War Monitor named West of Slavery one of the “Five Best Books” ever written on the war in the Far West. My second book, The Boundless Biddy Mason: An Odyssey from Slavery to Freedom Across the American West, will be published by University of California Press in fall 2026.Much of my work extends beyond the academy. My articles have appeared in the Atlantic, the Washington Post, National Geographic, Time, the New Republic, Slate, and the Los Angeles Times, among others. I consult for the National Park Service to identify and preserve historic sites of interest in the American West. We recently registered two new California sites in the National Underground Railroad Network to Freedom.
I also moonlight in TV and film. I co-wrote the eight-episode docuseries, “Pirates: Behind the Legends” (National Geographic, Hulu), and I’m currently writing and producing a six-episode series on the American Revolution for National Geographic and Disney+. Before that, I was the lead historical consultant on the Emmy-nominated docuseries “Frontier” (National Geographic, Paramount+). I appear as a talking head in six documentaries.
Before coming to UTD, I taught for nine years at Durham University in the U.K., where I remain an Honorary Fellow and an elected Fellow of the Royal Historical Society.
I’m delighted to be teaching talented undergraduate and graduate students at UTD, and I welcome inquiries from prospective grad students on a range of topics, including the history of the West, slavery and emancipation, the Civil War era, and American empire. I’m also actively seeking students interested in public history and filmmaking.
