After studying physics at the ENS Lyon, I did my PhD at the University of Paris-Sud in Orsay under the supervision of Asmaa Abada, working on tests of neutrino mass models through lepton flavour violating decays and lepton universality tests. From 2013 to 2015, I was a postdoctoral researcher at the IFT, Autonomous University of Madrid-CSIC, where I studied searches of heavy sterile neutrinos at LHC via their direct production and decays or through lepton flavour violating Higgs decays. Since October 2015, I have been working at the IPPP, extending my research to future colliders and low-energy experiments and further scrutinizing the connection between Higgs physics and neutrino physics.

Research Interests

My research interests focus on the interplay between direct and indirect tests of neutrino mass generating mechanisms. Neutrino oscillations have been confirmed more than a decade ago and they imply that neutrinos are massive particles, a fact celebrated by the Nobel Prize in Physics 2015. While many models have been suggested to generate the required neutrino masses and mixing, no unique solution has emerged. These models add new particles to the Standard Model that can be searched for at the LHC or future colliders. They will also lead to new signatures in high-intensity experiments like MEG, Belle II or NA48/62 and in cosmological observables. Combining various measurements will help distinguish models and improve our understanding of the mechanisms at the origin of neutrino masses and mixing.

Following the discovery of the Higgs boson at the LHC in 2012, a new field of investigation has opened. Recently, I have been particularly interested in the impact that neutrino mass models can have on the Higgs boson properties and electroweak symmetry breaking as well.

Recent Talks

A few recent talks:
Neutrinos and the Higgs, invited review talk at NuPhys 2017, London, UK, December 2017
Sensitivity of the triple Higgs coupling to heavy sterile neutrinos, talk at the DESY theory workshop, Hamburg, Germany, September 2017
Neutrino physics at colliders, invited review talk at the GDR Neutrino meeting, Paris, France, May 2017


I have recently developed a strong interest in outreach and enjoy talking to both students and the general public. While in Madrid, I have organised a field trip with high-school students to measure the atmospheric muon flux and demonstrate the effects of relativity on the muon lifetime for example. I have regularly given public lectures on particle physics and neutrinos. I had the recent pleasure to be a tour guide on the STFC-funded LHC roadshow exhibition during the Bluedot festival and to participate in the Royal Society Summer Science Exhibition 2017 (see our video here)
