My research areas include intimate relationships, sexuality, singlehood and online dating.
I’m the principal investigator of the French national survey “ENVIE” on young adults’ intimate relationships carried out in 2023 on a representative sample of more than 10,000 individuals aged 18-29 years. We published the first results in 2024 (https://www.ined.fr/fichier/s_rubrique/34826/623a.ined.en.pdf) and a book is coming soon (spring 2025).
Within the frame of this survey research, I’m particularly interested in casual relationships (e.g “hook-ups”, “sexfriends” and other sexual relationships of the sort), and more generally in the relational organization of sexuality.
I’m an expert on online dating and have been studying the usage of dating sites and apps since 2007. The main results of this project were published in the 2022 book "The New Laws of Love. Online dating and the privatization of intimacy" (Polity Press/Ined Editions), an extended version of a book initially published in French in 2019 (La Découverte). The project is ongoing.
I’m also interested in the measurement and experiences of singlehood, in the process of couple formation and in methodological questions regarding survey research and the use of big data in the social sciences.
