Julien Billard

Postdoctoral Associate Postdoctoral Scholar

I grew up in Mauritius island which is a beautiful and peaceful place with amazing beaches and sea sports opportunities. Then, I moved to Grenoble (France), which is well known for its surrounding mountains, where I did both my undergrad and grad school. I am now settled down in Cambridge, since August 2012 for my postdoctoral position at MKI.

Research interests: 

I am a postdoctoral associate in astroparticle physics. I joined the SuperCDMS collaboration which aims at directly detect Dark Matter from an underground experiment using cryogenic semiconductor detectors. Since recently, I am also interested in searching for coherent neutrino scattering and probing neutrino properties using very low energy threshold cryogenic detectors. During my Ph.D. I worked on directional detection of Dark Matter using gaseous TPC in order to measure both the energy and the track of recoiling nuclei in order to probe the ultra-local Dark Matter velocity distribution.
