Cyril Tordeur

Cyril Tordeur is a PhD candidate in Biomedicine and Pharmacy at the Université libre de Bruxelles (Belgium), specialising in space physiology and gravitational biology. His research focuses on cardiovascular adaptations to weightlessness, using ISS data, bedrest studies, and hindlimb unloading models. He employs techniques ranging from cardiac MRI and ECG to histology and biomolecular analysis. Cyril collaborates with international institutions like the German Aerospace Center (DLR) and Université de Montpellier. His key publications address cardiac adaptations to long-duration spaceflight, notably left ventricular papillary muscle atrophy. He was awarded first place in the 2025 Young Investigator Award of the International Society for Gravitational Physiology for his work on the NEBULA project (with the support of the French Space Agency - CNES). Formerly a physiotherapist in cardiac rehabilitation, he holds two Master's degrees and is a member of several physiological scientific societies.
