Scheidel's research focuses on ancient social and economic history, with particular emphasis on historical demography, labor, and state formation. More generally, he is interested in comparative and transdisciplinary approaches to the study of the premodern world, and is trying to build bridges between the humanities, the social sciences, and the life sciences.
