Claire Lemercier became a CNRS research fellow at the l’Institut d’histoire moderne et contemporaine (Institute for Early Modern and Modern History) in 2003, then joined the CSO in 2010.

Her research focuses on institutions that incorporate both public and private elements and which participate in regulating the economy. Her work aims to define a French model of regulation based on the unique relationship between public and private sectors.

After conducting an extensive study of commercial courts and labour relations boards, her latest projects delve into 19th century patterns of statecraft in the United States and France (with Nicolas Barreyre); the history of apprenticeship in 18th- and 19th-century France (with Clare Crowston and Steve Kaplan); governance changes in the largest French firms and their approaches to recruiting top managers, from the 1830s to today (with Pierre François); and notarial and other practices of formalisation in 18th-century Europe (with Francesca Trivellato).

A specialist in quantitative methods in the field of history—especially network analysis—Claire Lemercier has taught and published a great deal on these topics, often in collaboration with Claire Zalc. In 2019, they published Quantitative Methods in the Humanities: An Introduction (University of Virginia Press) and created a companion blog.
