Ling Hao

Ling Hao

Principal scientist

Prof. Ling Hao received the BSc degree in general physics and the MSc degree in solid state physics from Beijing Normal University, China. She moved to the UK in 1992 and received the PhD degree at the Department of Physics and Applied Physics, University of Strathclyde, UK, for research on electronic noise in superconducting devices in 1995. Since then she has worked at NPL. 

She is leading a team in the Quantum Technologies Department, researching into quantum sensors based on superconductivity, microwave resonators and nano-mechanical systems (NEMS). She is a Fellow of the Institute of Physics, Chartered Physicist and a visiting professor at Imperial College London. She was a guest professor at Fudan University (Shanghai) until 2018 and Harbin Institute Technology, China.  She has published more than 220 research papers in refereed journals as well as writing six book chapters. She holds two international patents in the area of SQUIDs and microwave detection. She was a member of the Institute of Physics Superconductivity Committee and is a Member of Editorial Board of IEEE Council on Superconductivity, responsible for Detectors. She was Guest Editor for Special Issue on NanoSQUIDs for ‘Superconducting Science & Technology’. She has managed many collaborative projects, both national and international including as co-ordinator for EU funded projects. In her time at NPL she has co-supervised more than 15 PhD students at universities including Imperial College, UCL, Manchester and Surrey Universities. 

Areas of interest

She is leading work on applications of superconducting electronics, nanoscience and microwave technology for quantum measurements and applications. The aim is towards quantum technologies leading to single particle detection and metrology using nanoscale Superconducting QUantum Interference Devices (nanoSQUIDs) and nanoelectromechanical system (NEMS) resonators. She is also prominent in developing graphene, quantum materials and other thin film transport measurement methods using patented microwave resonator techniques.
