Cécile Hébert

Cécile Hébert est née en France, en 1970. Elle a obtenu son diplôme d'ingénieure (option physique) puis son doctorat ("Etude d'un nouveau filtre d'énergie des électrons pour le microscope électronique à transmission") à l'Ecole centrale de Paris. Doctorante dans le laboratoire du professeur Jouffrey, elle a créé un nouveau filtre d'énergie des électrons, pour le microscope électronique à transmission, qui a été breveté par le CNRS. En tant que post-doctorante dans le laboratoire du professeur Schattschneider, elle a mené à bien une étude marquante sur la simulation des structures fines des seuils de perte d'énergie des électrons en comparaison avec l'expérience. En 2005, elle a été l'une des actrices principales dans l'élaboration du projet européen CHIRALTEM visant à développer dans le microscope électronique à transmission une méthode similaire à la méthode XMCD (X Ray Magnetic Circular Dichroism) connue en spectrométrie d'absorption des rayons X.

OPEN POSITIONS

Open position for a PhD thesis at the LSME/CIME EPFL, Lausanne, Switzerland in the field of: Experimental low loss electron energy loss spectrometry in transmission electron microscopy. The aim of the project is the accurate determination of the loss function by means of EELS in the TEM. It will require good experimental skills for the operation of the microscope in non conventional modes, initiative and imagination and a good understanding of the underlying physics (electron-matter interaction as well as electron detection system). Some programmation for data processing will be needed. The experiments will be complemented by theoretical investigation done in the group. Starting date: immediate or upon mutual agreement Highly motivated candidates are invited to send their CV, description of research experience, a short statement of research interests, copies of transcripts (courses followed and grades obtained) of undergraduate and Master studies, and contact information for 3 references to Prof. C. Hébert (cecile.hebert@epfl.ch)
