Kaat Louckx is a historical sociologist whose research explores how modern societies have come to know, govern, and represent themselves through structured practices of inquiry. Her work combines historical sociology, sociology of knowledge, and the history of science, with a particular focus on how statistics, questionnaires, and expert authority have shaped categories of citizenship, governance, and identity. She is currently preparing a new research project, Questions of Modernity, which proposes a longue durée investigation into the social and epistemic history of questioning practices across scientific, administrative, and security domains. Her work has appeared in journals such as The Sociological Review, Social Science History, Journal of Social History, and Nations and Nationalism. She is co-author of Sociology in Belgium (Palgrave Macmillan, 2018; Springer, 2023), serves on the editorial board of The American Sociologist, and is associated faculty at the Committee on Conceptual and Historical Studies of Science (CCHSS), University of Chicago.
