John Gallop

John Gallop is currently researching developments in nanoscience, including:

  • Transport properties of graphene and carbon nanotubes
  • Single particle measurements with nanoSQUID
  • Sub-micron Hall sensors
  • The metrology of nanoelectromechanical (NEMS) resonators

Biography

John joined NPL in 1969 following a DPhil in ultra-low temperature physics at Oxford University. He worked on metrology applications of macroscopic quantum aspects of superconductivity (involving fundamental constant determinations, SQUIDs and high frequency applications) for a number of years.

Later, he spent more than a decade on research into the applications of high temperature superconductivity.

John is an emeritus senior NPL fellow, has written over 200 papers and was head of the Quantum Detection Group until retirement in 2003. John is also a visiting professor at Imperial College and a Fellow of the Institute of Physics.
