Current interests

Jon is currently working on developing superconducting nanowire structures for a new current standard using quantum phase slips.

Biography

Jon Fenton received his MSci degree in natural sciences from the University of Cambridge in 1998 and a PhD degree from the University of Birmingham in 2002 for work on time-resolved measurements of heating in the high-temperature superconductor Bi-2212.

He continued to work on high-temperature superconductors on joining University College London as a postdoctoral research associate in 2004.

In 2009 he began working under a joint appointment with UCL and the National Physical Laboratory under the EPSRC/NPL postdoctoral research partnership scheme.

Jon is a member of the Institute of Physics.
