Dr. Julien Masbou

Assitant Professor at Nantes Université
IMT Atlantique


Julien Masbou joined the Xenon group at the Subtaech laboratory in 2012. His work is dedicated to astroparticle physics to answer fundamental questions about the Universe. Before moving to Nantes, he completed his PhD in gamma-ray astronomy studying new analysis techniques and indirect dark matter searches.

Julien is now mainly involved in the search for rave events with liquid xenon detectors. He continues his quest on fundamental questions of the constituents of the universe such as finding direct evidence for the existence of dark matter or studying the deep properties of neutrinos. He is an active member of world-class experiments: the XENON project is built to observe direct evidence for dark matter, Darwin is designed to be the ultimate detector with versatile physics objectives, and the nEXO experiment aims to be the most sensitive detector for the search for neutrinoless double beta with 136Xe.

Julien Masbou coordinates the recovery and storage working group for the XENONnT experiment and is the “”Dark Universe”” convener of the International Research Network in Particle Physics (Terascale). He is a member of the Public Relations Team of the XENON program. Julien is also an elected member of the board of directors of the French Physical Society. In 2022, he received the accreditation to supervise research (Habilitation à Diriger de Recherches) in Particle Physics from Nantes Université.
