Biographie
Après une thèse de doctorat sur la mesure de sections efficaces de réactions (p,n) sur accélérateur (IRSN, France), j'ai travaillé sur le développement de détecteurs et méthodes de mesure neutron pour la physique des réacteurs (CEA, France). Je suis en poste au LRS à l'EPFL depuis octobre 2014, en tenure track de l'Insitut Paul Scherrer depuis 2016, en tant que responsable des activités de recherche expérimentale sur nos installations.

Mon travail s'inscrit dans le cadre des activités expérimentales de recherche du LRS, détaillées sur ses pages : ici.
Mon travail actuel consiste à analyser le programme expérimental COLIBRI, dont la première phase s'est terminée en décembre 2019, et à préparer le prochain programme dans CROCUS : PETALE. Je co-encadre également deux thèse de doctorat sur le développement de mesures de bruit neutronique, et le développement de mesure neutron en cœur par fibre optique, ainsi qu'une thèse en collaboration avec le CEA en France portant sur la modulation neutronique en réacteur.
