I am a political sociologist working as a permanent research fellow at the Centre national de la recherche scientifique (CNRS – CREST) in France. I am also an Associate Professor at l’Ecole polytechnique.

I am regularly invited to teach in French and foreign universities. Over the last 5 years, I have held visiting professor positions at: ENS-Paris, Berkeley, University of Chicago, Sciences Po Paris, IDAES Buenos Aires, Linköping University, ENSAE, Chalmers Institute in Gothenburg.

I am also the editor (non-thematic issues) of Actes de la recherche en sciences sociales, a leading journal in the francophone space. And yes, you should definitely submit to it (even in other languages than French).

My current research focuses on the transformations of the political fields in Europe over the last decades, with a focus on the question of political professionalization. It draws on an extensive study carried out at the French Parliament, using both ethnographic material and digital data. A recent series of publications investigated the much decried « professionalization of politics, » in France since the 1970s. A first book, co-authored with S. Michon & J. Boelaert,  was published in 2017 under the title Métier: Député [Occupation: MP], and was widely discussed during the 2017 election season. Other articles have been published or are in print.

I also wrote several newspaper invited columns on this theme, including this double page in the French daily Le Monde on the newly elected parliament, or this one on the painful discovery of politics by political novices. I am currently writing a second book provisionally entitled The Candidates. Novices and Professionals in Politics.


My previous work dealt with the French « War on Cults, » which saw the country wage an intense battle against these groups for more than three decades. It was published by La Découverte in 2017, under the title Raison d’Etat. Histoire de la lutte contre les sectes [Reason of State. A History of the French War on Cults].


I am also invested in the fastly developing field of computer social sciences. In the last years, I have reflected on digital data and their use for (social) sciences, for instance by critically investigating the so-called big data revolution. I regularly make use of computational methods to collect, format and analyze data (such as in this paper on the Superiority of Economists, co-authored with Marion Fourcade & Yann Algan, or in this one on the reception of French sociologists in the USA, with Andrew Abbott).

Part of this work deals with with machine learning. One of my interest is to clarify  what can social sciences do with it, and conversely what it can do to them. The first article about this project, co-authored with J. Boelaert, was published in  the Revue Française de Sociologie under the title « The Great Regression. Econometrics, Machine Learning, and the Future of Quantification » (get it here).


Currently, I am exploring the transformations of political journalism and of the public debate am using state-of-the-art Natural Language Processing tools (which, let’s face it, I am not sure I fully master – but I have talented collaborators).

Eventually, I dedicate part of my time to spreading the computational social science gospel, teaching social scientists how to collect, format and analyze digital data in various forms. To this effect, I regularly organize intensive workshops on the topic, in France or abroad.
