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. From Aug. 2011, 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 August 2017 as a lecturer 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 am a Visiting Lecturer at the University of Stratchclyde (2022-2025) and was a visiting researcher at the Advanced Technology Institute (ATI), University of Surrey in 2017. I was a member of the European Microwave Association (EuMA) General Assembly (GA) representing Group 4 (United Kingdom, Ireland, Gibraltar, Malta) between 2018 and 2021. I was the Chair of Workshop & Short Courses of EuMW2021 and I am an Associate Editor for Royal Society Open Science since 2017. 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:

PhD projects

  • Making the quantum computers wireless 

    The first computer ENIAC, which was invented 75 years ago, occupied 170 square meters and weighted almost 50 tonnes. Nobody at the time would imagine how computers could be evolved to what they look like today. Quantum computing, which is believed to be one of the most significant revolutions of 21st century is still at its dawn, facing the same challenges as first computers did half a century ago: bulky, expensive, and difficult to operate. We are here at Glasgow University bold and ambitious! Funded by EPSRC’s WiQC and EPIQC projects, we will take a risky but potentially rewarding step for the next generation of quantum computers: making the quantum computers wireless. Want to be part of this? Please get in touch.

  • Pushing the limits of low noise amplifiers: from semiconductor materials, device physics, nanofabriacation to circuit design

    Low noise amplifiers (LNAs) are the most important components of all RF systems such as communications, RADAR, astronomy observation, and remote sensing. The conventional key performance parameters of LNAs include noise figure, gain, linearity, and bandwidth. However, the recent advance of quantum computer systems has added another performance factor: DC power consumption which makes development of LNAs even challenging. In this project, you will take advantage of Glasgow University’s world leading nanofabrication and test facilities (JWNC and ESDC) and continue Glasgow University’s legacy on transistors flourish again.

  • GaN-based diodes and tranistors for water and gas sensing

Ionic pollution in water and concentrations of gases, vapours and volatile organic compounds in air are becoming threads to human health, food safety and environments. GaN-based field effect transistor (FET)-based sensors have recently been demonstrated a viable solution due to their high sensitivity to the surface charge. However, the current technologies e.g. GaN transistors require tens of milliwatts which are not sustainable in many applications. In this project, we aim to reduce power consumptions of the sensors by at least two orders via co-optimisation of devices, circuits and systems.

  • Compact monolithic integrated circuits for Beyond5G/6G wireless communications   

With commercial 5G networks rolling out globally from 2019 onwards, the agenda for research into next-generation mobile communications has become a priority for academia and industry. One of the main challenges in cracking future communication systems is highly efficient RF front-end or transceiver. As the operating frequencies of future communications move into the millimetre wave domain, e.g. 30 GHz and above, the performance of electronic devices such as amplifiers and passive component integrated circuits will degrade in a number of ways, including lower efficiency, higher power consumption and poor integratability. In this project, you will take advantage of Glasgow University’s world leading nanofabrication and test facilities (JWNC and ESDC) and devise, fabricate and test compact transceivers operating at 110 GHz and above.

  • Development of wireless charging technology for wireless sensor nodes

    Wireless sensor nodes (WSN) have been found in many applications including environment monitoring, building structural health checks, and personal medical diagnosis etc.  In most cases, sensor nodes are powered by built-in batteries which are bulky and can only last for short time. Replacing batteries can be very expensive or impossible in some scenarios. In the past decade, many energy harvesting approaches converting ambient energy e.g. solar, thermal, and acoustics to power WSNs have been studied; however, they face various limitations, e.g. weather conditions, size, distance, and communications. RF/microwave signals e.g. GPS, WiFi, 4G/5G are nowadays everywhere and they have the advantage of low attenuation in air and being less affected by weather conditions. That makes them suitable for long distance applications; however, RF/microwave signals suffer from high loss in water or inside human bodies. To use them in those conditions, different media such as ultrasound has to be implemented. In this project we will investigate a novel hybrid microwave-ultrasound transducer for both energy harvesting and wireless communications. We will tackle the challenges of RF/Microwave sensing, RF/Microwave to ultrasound frequency conversion, and ultrasound transducer efficiency. The candidate student will investigate new material, device modelling, circuit design and micro/nano fabrication. Finally, a hybrid transducer with integration of CMOS sensors will be tested for underwater monitoring or/and medical diagnosis.
