Biography

I obtained a PhD degree in Electronics and Electrical Engineering from the University of Glasgow in 2012. My PhD involved developing monolithic millimetre-wave signal sources and integrated circuits. Following my PhD I took up a post as a Postdoctoral Research Assistant, and later a Postdoctoral Research Associate at the University of Glasgow, working on development of terahertz imaging systems. I joined the National Physical Laboratory (NPL) in January 2014 as a Higher Research Scientist. I rejoined Glasgow University in 2017 as a lectuer and found the Microwave and Terahertz Electronics (MaTE) group. I am the Director of Electronic System Design Centre (https://www.gla.ac.uk/research/az/esdc/) and managing the Microwave and Terahertz Laboraotory (see below for further details).

I held a visiting position at the Advanced Technology Institute (ATI), University of Surrey in 2017. I am a senior member of IEEE and a member of the European Microwave Association (EuMA) General Assembly (GA) representing Group 4 (United Kingdom, Ireland, Gibraltar, Malta). I am the Chair of Workshop&Short Courses of EuMW2021 and an Associate Editor for Royal Society Open Science. I've served as a member of the technical programme committee for several conferences. I won the best paper twice at Loughborough Antennas and Propagation Conference (LAPC).

Research interests

I am leading the Microwave and THz Electronics (MaTE) Group and interested in:

III-V (InP/GaAs and GaN) semiconductor devices and processes
MMICs and TMICs
emerging materials and technologies for wireless sensing, imaging, communications and energy harvesting;
metrology for antennas and propagation; and
metrology for on-wafer measurements.

Summer students, final year/MSc project students, self-funded/government-funded PhD students are welcome to my group. Please contact me if you have any brilliant ideas about any of the above listed topic(s) or something else.
