PhD and Postdocs

A “TREASURE PhD student” is a student preparing his PhD under the co-advisoring of two partners of the network. This way, she/he may beneficiate of expertise from different fields which each partner is specialized on and can take advantage of exchanges under the form of training periods opportunities during her/his PhD. The informations given in the following pages are only related to the period during which the person was preparing his/her PhD. For any further information, please contact directly the person or Jérôme Harmand who will forward your question...
