In France we have several groups working on the field of NVH. Here is a short list, many other names and laboratories exist. I am not affiliated to any of them.
In Paris, you have a famous and scientifically strong university called Ecole Normale Supérieure (ENS) Paris Saclay, where the SATIE lab is efficiently working on the field. http://satie.ens-paris-saclay.fr/version-anglaise/home/ You can look at publications from BEN AHMED Hamid, BLAVETTE Anne, DE LA BARRIERE Olivier, GABSI Mohamed, HLIOUI Sami, HOANG Emmanuel, IDKHAJINE Lahoucine, LE BALLOIS Sandrine, MULTON Bernard, OJEDA Javier, PREVOND Laurent RUELLAN and Marie VIDO Lionel
A bit norther, in Compiegne at the Université de Technology (UTC), few researchers focus almost exclusively on NVH at the LEC. http://www.utc.fr/lec/ You can look at publications from LANFRANCHI Vincent and FRIEDRICH Guy
Again norther, in Arras, you have the Université d’Artois where there is the LSEE. http://www.lsee.fr/Site/index.php/en/ You can look at publications from Jean-François BRUDNY, Bertrand CASSORET, Emile DEVILLERS and Jean-Philippe LECOINTE
Still North, in Lille, you have Ecole Centrale, where the L2EP is located. http://l2ep.univ-lille.fr/?lang=en You can look at publications from Michel HECQUET and Pascal BROCHET
It is worth nothing that we have companies dedicated to the subject of NVH, that work very closely with universities since we do not have a fully dedicated university laboratory on the field of NVH. Thus, companies like EOMYS (see publications of Jean LE BESNERAIS) and VIBRATEC (see publications of Jean-Baptiste DUPONT) link various labs to create common subjects.
As you can see, our French websites are terrible, with an awful non-modern design, often not at all translated, and lacking a lot of information. It must mean that they work hard on their subject rather than cosmetics ;-) If you need help and further details, you can ask.
Thanks Guillaume Verez for taking your time in listing down the universities backing up with details. I guess the opportunities are quite limited for international aspirants?
You're welcome. While all researchers publish in English, most (if not all) of the labs work in French on a daily basis. Though, I see no reason to not try to reach the labs and try to find a position. Most of the time, the PhD candidate has previously worked with the lab/university/professor or a place that has good connections with it. A postdoc position is more easily reached when you do not have the network.
