Alec Dun is an early American historian. His scholarly interests—in race and identity, radicalism and revolution, slavery and antislavery—lead him to focus particularly on the eighteenth and early nineteenth centuries in America. Those same interests, however, widen the boundaries of that “America” to include the Caribbean and, in some ways, the greater Atlantic basin as a whole.

Dun received his BA from Amherst College and his MA and PhD from Princeton. His first book, Dangerous Neighbors: Making the Haitian Revolution in Early America was published by Penn Press in 2016. He taught in the University's History Department for 13 years, and was an Associate Editor at the Papers of Thomas Jefferson. He is currently Associate Dean of the College.
