Academic Experience
- 2024 02 > 2025 01 Postdoctoral researcher, JSPS, The University of Tokyo.
I aim at building a socio-informatics mapping of goals and characteristics of music recommender systems. As a JSPS fellow, I am affiliated at the Graduate School of Information Science and Technology and the Japanese-French Laboratory of Informatics, under the co-supervision of Ryohei Hisano and Philippe Codognet. - 2023 08 > 2023 12 Research assistant, ERC Socsemics, Centre Marc Bloch, Berlin.
I was in charge of the qualitative part of a study of the political participation on Twitter in 2020 (15 interviews), within the computational social science team, under the supervision of Camille Roth (CNRS). - 2018 11 > 2023 10 PhD candidate, CNRS, Centre Marc Bloch.
I studied the manufacture, the design and the use of recommender and decision-making systems in organisations (100+ interviews), under the supervision of Camille Roth and Francis Chateauraynaud (EHESS). I was funded by a CNRS doctoral contract.
During my PhD, I paid a visit to the Maison française d'Oxford (2023), the French-australian laboratory for human-autonomous agents teaming (CROSSING), Adelaide (2023) and the National Taipei University of Education, Taiwan (2022), I reviewed papers for the ACM Conference Designing Interactive Systems in 2021 and 2022, co-organised a writing workshop (2020) and co-supervised two interns, Jonas Stein and Quentin Villermet (2020). At Centre Marc Bloch, I was also a doctoral students representative (from 2019 to 2021). Finally, I gave some classes in sociology and project management at Télécom St-Etienne, France (2018, 2019) and in digital cultures at the Humboldt University, Berlin (2019). - 2017 > 2018 Research assistant, ANR Algodiv, Centre Marc Bloch.
I led a qualitative study of the manufacture of recommender systems by engineers (30 interviews), under the supervision of Camille Roth.

PhD Thesis
- 2023 The Design of Algorithms: Manufacture and Impact within Organizations. A Sociology of Engagement and Disengagement Processes in a Computational Regime.
Supervised by Camille Roth and Francis Chateauraynaud. Defended at the School of Advanced Studies in the Social Sciences (EHESS), Paris, before a committee composed of Cécile Méadel (president), Jean-Samuel Beuscart (reviewer), Antoinette Rouvroy (reviewer), Nicolas Benvegnu, and Thierry Ménissier.
This thesis aims to take a pragmatic look at the "algorithmisation" of recommendation and decision-making within organisations. It lies at the intersection of research that explores the use of automation and evaluation technologies in organisations and that which questions the intentions and opacity of algorithms. Starting from the premise that the initial step in algorithmisation is the "datafication" (sometimes massive) of consumption and decision-making activities, we draw upon the concept of "algorithmic governmentality" to examine how designers and users of algorithms harness them to achieve their objectives.To accomplish this, we conducted four studies involving around a hundred actors (initiators, engineers, digital designers, and users) of recommendation algorithms and organisational algorithms. We demonstrate, in particular, that initiators employ algorithms – crafted by engineers and digital designers – not to automate actions but to disengage from any cultural or decision-making prescription. Consequently, it falls upon users to make choices and become engaged. In the case of recommendation, algorithm evaluation is oriented towards consumption, while for decisions support, priority is given to utility and interpretability of results. This conclusion suggests the emergence of a "satisfaction regime," providing an optimal framework for initiators to align objectives related to organisation and use.
Degrees
- 2023 PhD in sociology, School of Advanced Studies in the Social Sciences (EHESS), Paris.
- 2017 Master in social sciences, major in design and information architecture, École Normale Supérieure of Lyon.
I did an internship and wrote the master thesis "An Experiment to Visualise Socio-semantic Confinement on Twitter" under the supervision of Camille Roth (2017), which was the start of the research journey with him. I spent one Erasmus semester at the University of Oslo, and took classes in design and education (2016).
- 2014 Bachelor in communication studies, major in journalism, University Paris VIII (in collaboration with Radio France).
- 2013 Advanced technical degree in audiovisual studies, major in production management, National Audiovisual Institute, Paris.
Non-academic skills
- I can work in English, French and German, and order food in Japanese (いただきます).
- Although it's being a while (2016), I am a proud co-founder and first co-president of two French non-profit organisations, Designers Éthiques and Éditions Kaïa.
The former (still) promotes sustainable digital design. In the beginning, we mainly organised events under the brand Ethics by design, including the first one in Lyon (2017) and a bigger one in Paris (2018). Besides, we managed a community of designers.
With Éditions Kaïa, my enthousiastic mates and I printed online journalistic stories on high quality paper booklets, we then shipped to loyal subscribers. Unfortunately, the project has been paused in 2019.
These two experiences probably find their roots in the modest consulting activity I co-managed while studying in Lyon (2015).
