Ancel Prize 2012 awarded to Odile Stéphan

The Louis Ancel Prize of the French Physics Society was awarded to Odile Stéphan in acknowledgment of the importance and the quality of her scientific production and of her national and international recognition.


Odile Stéphan did her PhD in the Laboratoire de Physique des Solides (LPS) in Orsay under the direction of Christian Colliex, graduating in 1996. After a postdoctoral stay in Tsukuba (Japan), she obtained an Assistant Professor position at the Paris-Sud University in 1997. She is now a full Professor in the same university.



Odile Stéphan’s research focuses on nanomaterials and nanostructures. More precisely, she developed and used over the years sophisticated methods of analytical electronic microscopy. She worked on a wide range of problems related to various materials : from carbon nanotubes to plasmonic nanostructures, catalytic nanoparticles and molecular magnets.

As a pioneer in the field of Electron Energy Loss Spectroscopy, she showed that these technique can be used to study the optical properties of materials with unprecedented spatial resolution.

Since 2009, Odile Stéphan is in charge of the STEM team of the LPS. She is the leader of the EquipeX TEMPOS project which will bring three last-generation electronic microscopes on the Paris-Saclay campus. She was a member of the Conseil National des Universités and of the Comité National de la Recherche Scientifique.
