Scheidel's research ranges from ancient social and economic history and premodern historical demography to the comparative and transdisciplinary world history of inequality, state formation, and human welfare. He is particularly interested in connecting the humanities, the social sciences, and the life sciences.
The most frequently cited active-duty Roman historian adjusted for age in the Western Hemisphere, Scheidel is the author or (co-)editor of 20 books, has published well over 200 articles, chapters, and reviews, and has lectured in 27 countries. His most recent books are The Science of Roman History: Biology, Climate, and the Future of the Past (2018, ed.), The Great Leveler: Violence and the History of Inequality from the Stone Age to the Twenty-First Century (2017; 12 translation contracts), On Human Bondage: After Slavery and Social Death (2017, co-edited with John Bodel), State Power in Ancient China and Rome (2015, ed.), Fiscal Regimes and the Political Economy of Premodern States (2015, co-edited with Andrew Monson), The Oxford Handbook of the State in the Ancient Near East and Mediterranean (2013, co-edited with Peter Bang), The Cambridge Companion to the Roman Economy (2012, ed.), The Oxford Handbook of Roman Studies (2010, co-edited with Alessandro Barchiesi), Rome and China: Comparative Perspectives on Ancient World Empires (2009, ed.), The Dynamics of Ancient Empires (2009, co-edited with Ian Morris), and The Cambridge Economic History of the Greco-Roman World (2007, co-edited with Ian Morris and Richard Saller).
Scheidel just finished a book on the connections between the fall of the Roman empire and the creation of the modern industrialized world, which will come out later this year, and the co-edited The Oxford World History of Empire (2 vols., with Peter Bang and Christopher Bayly). His next book project is a global history of monogamy from hominin evolution to the present. He is also planning an e-publication on the Roman monarchy in global comparative context and a concise survey of ancient demography. He launched an international research initiative for the comparative study of ancient Mediterranean and Chinese empires, co-founded the Princeton/Stanford Working Papers in Classics, created the interactive web site Orbis: The Stanford Geospatial Network Model of the Roman World, which has attracted about a million visitors and global media coverage, and is a co-editor of the monograph series Oxford Studies in Early Empires and a former editor of the journal Historia. He was awarded a New Directions Fellowship of the Mellon Foundation and a Guggenheim fellowship, and is a Corresponding Member of the Austrian Academy of Sciences.
