JT Janssen

JT Janssen was born in the Netherlands in 1965. He received the MS and PhD degrees in physics from the University of Nijmegen, The Netherlands, in 1989 and 1994, respectively. His doctoral work was on the far-infrared magneto-optical properties of low dimensional semiconductor structures and organic conductors. From 1994 to 1998, he was a Research Fellow at the University of Bristol, Bristol, UK, investigating the Fermi surface properties of heavy Fermion metals and superconductors using the de Haas-van Alphen effect.

JT has been at NPL since 1998, he is responsible for the research on quantum electrical standards.

JT is an NPL Fellow and a Fellow of the Institute of Physics.


JT is the contact person for NPL on the technical committee for electricity and magnetism (TCEM) of the European Association of National Metrology Institutes (EURAMET, convenor of the EUROMET DC quantum metrology experts group, and a member of several CCEM and EURAMET working groups.
