Personal statement

I received the B.Sc. degree in applied physics from the University of Science and Technology of China, Hefei, China, in 2004 and the M.Sc. degree in application of nuclear techniques from the China Academy of Engineering Physics, Chengdu, China, in 2007, and the Ph.D. degree in physics from the University of Strathclyde, Glasgow, UK in 2012.

As a researcher, I have experience working on a variety of research projects including gyrotron travelling wave amplifiers, plasma filled microwave sources, microwave pulse compression and free electron lasers. I have led the development of gyro-TWAs in terms of design, computational simulation techniques and laboratory experimentation. I have carried out world-leading experiments of high power broadband mm-wave/THz amplifiers that have great potential in EPR/DNP and mm-wave wireless and satellite communications. I have successfully demonstrated a world-record 88-104GHz continuously tuneable, high power (10kW) Gyro-BWO experiment (2012), and a gyro-amplifier achieving 3.4kW with a 3dB instantaneous frequency bandwidth of at least 5.5GHz at W-band (2017).
