Alexandra Houssaye is a Palaeontologist at the National Museum of Natural HistoryShe is director of research at the CNRS, in the MECADEV laboratory (adaptive mechanisms and evolution) at the MNHN. A palaeontologist by training, she is a researcher in functional morphology and studies the adaptations of the skeleton during the evolutionary history of amniotes.

A bone specialist, she focuses on the biomechanical adaptations of external and internal bone structures. Her goal is to better understand the form/function link in present-day organisms in order to make inferences from fossil organisms and thus to better understand how the skeleton, and thus organisms, adapted to significant changes in biomechanical constraints during their evolution.

She is one of 46 researchers and teacher-researchers at the Centre de recherche en paléontologie in Paris. It is a laboratory entirely dedicated to palaeontology. It is under the triple supervision of the Muséum national d'Histoire naturelle (MNHN), Sorbonne University and the CNRS (INEE). 

Alexandra Houssaye is the author of a thesis

He is currently leading 3 theses
