I'm a sociologist and research fellow at INSERM (CERMES3, Villejuif). I'm interested in the emergence of public debates and public attitudes to science on medical issues. My approach lies at the intersection of political sociology, the sociology of science and the sociology of cognition and representations. My work has focused mainly on vaccination in France, but also on a range of other subjects such as the prescription of hydroxychloroquine as a treatment for Covid-19, public perception of what constitutes a conflict of interest, and of clinical trials.

Since 2020, I have been an expert member of the Commission Technique des Vaccinations at the Haute Autorité de la Santé. I am also a member of the board of the 'Science and Technology in Society' thematic network of the French Sociology Association.

Ongoing projects

Since 2023, I lead the AMèS project (L'autorité de la médecine scientifique à l'épreuve des controverses sur la recherche clinique, funded by : ANR), which focuses in particular on the impact that controversies about clinical research can have on public attitudes to medical knowledge.

Since 2023, I co-lead the ICOVAC-France project (Impact de la Covid-19 sur la vaccination en France, funded by ANRS-MIE) with Patrick Peretti-Watel (INSERM, UVE). This project is looking at current developments in the mobilisation and controversy surrounding vaccines, ordinary relationships with vaccines and the vaccination practices of healthcare professionals in France.

The SHS-Vaccination France network:

As part of the ICOVAC-France project, we have set up the SHS-Vaccination France network to encourage contacts, exchanges and collaborations between researchers interested in the human and social aspects of vaccination in France and elsewhere.
