Jean-François Roch (Professor at ENS Paris-Saclay, LuMIn) is a world leader in NV-center diamond quantum sensors. Research: (1) NV center magnetometry — scalar and vector magnetic field sensing with ensembles and single NV spins; (2) NV centers in diamond anvil cells for high-pressure magnetometry (world record 240 GPa); (3) joint laboratory (JRL) with Thales R&T on industrial NV quantum sensors; (4) color centres in hBN. IUF Senior Member 2021; Jaffé Prize + Berthelot Medal 2024.
