Expertise

Mission

Je suis responsable des activités de recherche expérimentale du LRS à l'EPFL, principalement sur le réacteur expérimental CROCUS et la cavité d'irradiation LOTUS. Je suis également adjoint du Chef des installations nucléaires O. Pakari. Enfin, j'enseigne à destination des étudiants de Physique et en particulier du Master en Génie nucléaire, par le cours de Détection de rayonnements, et les travaux pratiques sur le réacteur et dans nos installations.
Je suis actuellement membre du Conseil de Faculté des Sciences de base, et ce depuis 2016.

Biographie Publications Enseignement et PhD

J'ai effectué ma thèse de doctorat sur la mesure de sections efficaces de réactions (p,n) sur accélérateur à l'IRSN, suivi d'un postdoctorat sur le développement de détecteurs neutron pour la physique des réacteurs au CEA, les deux en France au centre de recherche de Cadarache. J'ai été recruté par Andreas Pautz pour prendre la direction des activités expérimentales du LRS, et en particulier relancer les expériences sur le réacteur nucléaire CROCUS. Je suis en poste à l'EPFL depuis octobre 2014, en double affiliation avec l'Institut Paul Scherrer depuis 2016, où j'ai soutenu ma tenure en 2020.
