Xiaobang Shang

Principal scientist

Xiaobang Shang attained a BEng degree (First Class) in Electronic and Communication Engineering in 2008 and a PhD degree in Microwave Engineering in 2011 from the University of Birmingham. After graduating he continued working at the University of Birmingham as a Research Fellow.

In 2017, Xiaobang joined the NPL as a Senior Scientist, researching into electrical measurements at microwave, millimetre-wave, and terahertz frequencies, for future telecoms and quantum applications. He was promoted to Principal Scientist in 2023. He was the Coordinator for EMPIR TEMMT project (2019 – 2022), a large-scale EU metrology project involving 19 partners globally.

Dr Shang is a Visiting Professor at the University of Manchester (School of Engineering) and a Senior member of the IEEE. He has authored or co-authored over 120 publications. He was the recipient of several prestigious awards including the Roberto Sorrentino Prize in 2022, the IEEE Tatsuo Itoh Award in 2017, the ARMMS Steve Evans-Pughe Prize in 2017, and the ARFTG Roger Pollard Microwave Measurement Student Fellowship in 2009.
