Professor Jan-Theodoor Janssen FREng

Chief Scientist, National Physical Laboratory

Professor Jan-Theodoor (JT) Janssen is the Chief Scientist of the National Physical Laboratory (NPL). He is distinguished for the application of quantum technologies. His novel development of quantum electrical metrology systems and science placed NPL at the forefront of advances, leading to the international redefinition of the electrical measurement units in the SI system in 2019. For more than 20 years, JT has demonstrated extraordinary leadership in the understanding and practical application of quantum devices and quantum effects in materials such as graphene. This work is helping the UK become a world-leader in quantum technology.
