SN2NS is a 4-year program of the French agency ANR whose goal is the modeling of stellar core-collapse, leading to the birth of neutron stars and black holes. It involves three laboratories :

The program SN2NS, sponsored by the French "Agence Nationale pour la Recherche" (ANR), is advertising three postdoctoral positions for the period 2011-2014.
The expected starting date is September 1, 2011, though earlier starting dates can be accommodated.
Required application materials include a CV, bibliography, a statement of research interests and three letters of reference.
All applications arriving before February 1, 2011 will be fully considered. Later applications will be considered until the positions are filled.
