Her research addresses bodily themes (puberty, appearance, maternity, breasts, menopause, pleasure and sexuality, sexist and sexual violence) within the framework of phenomenological feminism that thinks women's bodies in the context of alienation and emancipation. She is the author of several works, including La révolution du féminin (2015, Folio 2020), Le corps des femmes. La bataille de l’intime (2018, Points 2021), Seins. En quête d’une libération (2020, Points 2022), Un corps à soi (Seuil 2021) et Un si gros ventre. Expériences vécues du corps enceint (2023), as well as her first novel, Pleine et douce (Sabine Wespieser Éditeur, 2023).
