Congratulations to Dr. Jean-Léon Maître, recipient of the Richard Lounsbery Award


Dr. Jean-Léon Maître, head of the Mechanics of Mammalian Development team, has been honored with the prestigious Richard Lounsbery Award by the French Academy of Sciences and the American National Academy of Sciences (NAS). The award recognizes the research carried out by his team to understand the mechanisms underlying the construction of the mammalian embryo.

The Richard Lounsbery Award has been presented each year since 1979, alternately to a French and an American researcher. It is intended to reward "outstanding achievements by French and American scientists" in biology and medicine, to stimulate these fields of research and encourage Franco-American scientific exchanges.


This year, Dr. Jean-Léon Maître, head of the Mechanics of Mammalian Development team (CNRS UMR3215 / Inserm U934 / Sorbonne Université), has been awarded the distinction for his studies on the origins of the forces responsible for cell deformation and displacement within mammalian embryos, including humans.

With his team, they meticulously studied the mechanical properties of the embryo prior to its implantation in the maternal uterus. This research led them to discover, among other things, the fundamental physical mechanisms governing the positioning of the first axis of symmetry of mammalian embryos, which is crucial for their attachment to the uterus.


Receiving the Richard Lounsbery Award is a tremendous honor that will hopefully shed light on the fascinating processes by which cells sculpt our bodies. We understand the shaping of mammalian embryos much better thanks to collaborations between scientists with a wide range of expertise and disciplines, from biology to physics and medicine. This is the very essence of the Curie model.

 Confides Jean-Léon Maître.
