I am a labor historian primarily interested in ruling class organizations and violence in the late nineteenth and early twentieth centuries. I have authored two books: Capital's Terrorists: Klansmen, Lawmen, and Employers in the Long Nineteenth Century (University of North Carolina Press, 2022) and Reform or Repression: Organizing America's Anti-Union Movement (University of Pennsylvania Press, 2016). Additionally, I am co-editor of Against Labor: How US Employers Organized to Defeat Union Activism (with Rosemary Feurer; University of Illinois Press, 2017). Finally, I have published essays in Counterpunch, History Compass, Jacobin, Journal of Labor and Society, Labor History, Labour/Le Travail, and Monthly Review.
