Dr Julien BONEFACINO
Research engineer
julien.bonefacino@college-de-france.fr
Julien obtained his PhD from The Hong Kong Polytechnic University in 2017, focusing on the development of polymer fibre Bragg grating (FBGs) sensors for medical applications. He continued his work at PolyU as a postdoctoral fellow working on heartbeat and respiration measurements using polymer fibre Bragg grating sensors. In 2018, his research interest switched to battery monitoring using fibre optic sensors. In June 2022, he joined the CSE as a research engineer focusing on battery monitoring using fibre optic sensors, and the transition of those fundamental researches into industrial applications.
