Jean-Louis Fabiani (born May 30, 1951)[2] is a French sociologist, professor of sociology and social anthropology at the Central European University, and the director of studies at the Centre d'études sociologiques et politiques Raymond Aron at the École des Hautes Études en Sciences Sociales.

[4] Fabiani's research has addressed the study of what he calls "configurations of knowledge" understood as the ways in which disciplines and scientific institutions are built and how they change.

This problem was the subject of his book Les philosophes de la République (1998) published by Les Éditions de Minuit in the collection "Sens commun" (compiled by Pierre Bourdieu).

[6] Fabiani is presently a senior professor at the Central European University in the department of sociology and social anthropology, a position he has held since 2011, as well as full professor and director of studies at the École des hautes études en sciences sociales.

In 2014, Fabiani was the Fernand Braudel Fellow at the European University Institute in the department of history and civilization.
