Personal Statement
I received the B.Sc. (Hons.) degree in physics from the University of Strathclyde in 2004, then the MSc degree in high power radio frquency science and engineering from the same institute. Following this I received the Ph.D. degree in 2009 in physics from the University of Strathclyde.
In the proceeding years I have been working as a researcher within the Atoms, Beams and Plasmas group within the physics of the University of Strathclyde. My research interests lie in realizing high power mm-wave and THz gyrotron amplifier and oscillators. These have many applications, such as a source for EPR/DNP, telecommunication and space object identification. Through this research world leading microwave output has been demonstrated initially with a gyrotron backward wave oscillator showing 88-102 GHz tunable microwave output with power of 13 kW. Later a gyrotron traveling wave amplifier was developed that showed 90-96 GHz amplification bandwidth with 3.4 kW output power.
Currently, work is ongoing to explote the applications of these devices to real-world situations.
Research Interests
Broadband, high power, mm-wave/terahertz gyrotron travelling wave amplifiers for telecommunications and space object identification; Gyrotron backward wave oscillator; Electron beam generation; Beam-wave interaction; novel manufacturing techniques; electrodeposition and electroforming; and pulsed power technologies.
