Research

This section presents the main inquiries I have conducted or am conducting, with some of their materials and the publications that came out of them.

Since 2025

Ex machina. The making of open-source LLMs

Public debate focuses on the AI giants. Yet much of the production runs through so-called “open” AI, which people can run on their own servers or computers. Starting from Hugging Face, this inquiry studies how these models are made and circulated, and what unequal access to computing changes.

With Nicolas Berkouk, a mathematician, and Anna Charles, a machine learning engineer, in collaboration with LINC, the CNIL’s digital innovation lab.

EL2MP. Ecologies of LLM Practices

EL2MP studies how language models enter work practices through a collective, participatory inquiry. Workshops, exercises and notebooks document what people delegate, check and reorganize with these tools.

At the Sciences Po médialab, with the designers Donato Ricci and Tommaso Prinetti.

Git. The industrialization of software writing

Git is the software most developers now use to write code together: it keeps track of every change, who made it and when. Following how Git is made and used, this inquiry analyses how the collective writing of code, the control of work and the relations between free software and the software industry are organized.

PhD at EHESS (Centre Maurice Halbwachs), supervised by Emmanuel Didier, a sociologist, and Christophe Prieur, a computer scientist and sociologist.

Work with me

My current interests include:

  • automation as an active gesture, something people practise;
  • qualitative methods in the age of artificial intelligence;
  • mathematics and computer science in an age of massive automation.

If you would like to work with me on these topics, in sociology and anthropology but also in interdisciplinary collaborations, I invite you to contact me. This can take the form of an internship, a research assistant position, master’s thesis supervision, PhD co-supervision, etc. Funding opportunities depend on current projects.

About

I am a sociologist at Inria and an associate researcher at the Sciences Po médialab. I investigate automation as a process, from its production to its enactment and its consequences, in fields ranging from free software to artificial intelligence.

Before joining Inria, I was a postdoctoral researcher at Sciences Po and a lecturer at Université Gustave Eiffel. A former student of the École normale supérieure, trained in sociology and statistics (ENS, ENSAE), I completed my PhD at EHESS (2022); my work received the Young Author Prize of the journal Sociologie du travail.
