Cécilia Bognon-Küss is a philosopher by training and a specialist in the history and philosophy of life sciences. She is currently an assistant professor at Sorbonne University, within the Philosophy Department, attached to the research unit “Sciences, Norms, Democracy“ (UMR 8011). She is responsible for the Master's programme in Biomedical Humanities in the Philosophy department at Sorbonne University and is deputy director of the Institute of Global Health at Sorbonne University.

Her research examines the conceptual and historical foundations of biological and medical sciences, with a particular focus on the concepts of nutrition, biological individuality, metabolism, environmental health and the relationship between organisms and their environment. Her approach, which combines the history of philosophy, the history of science and the philosophy of contemporary science, is based on constant dialogue between disciplines.

Her work has been published in numerous peer-reviewed international journals, including History and Philosophy of the Life Sciences, Kairos and Cahiers François Viète, as well as several collective works published by Vrin, Hautes études médiévales et modernes, History, Philosophy and Theory of the Life Sciences, International Archives of the History of Ideas and the Encyclopedia of Early Modern Philosophy and the Sciences. She has edited or co-edited several special issues of national and international journals, notably on the concept of biological organisation (HPLS) and the work of Georges Canguilhem (Archives de Philosophie). She has also co-edited a book published by Routledge on the philosophy of biology before the discipline was institutionalised (Philosophy of Biology before Biology, 2019). She is currently completing the publication of her thesis with Classiques Garnier, entitled Les racines métaboliques du vivant.
