Overview

Overview

I am a Senior Lecturer in Power Management in Energy Harvesting Systems. Before my current appointment, I was a Senior Research Fellow with the Energy Harvesting Research Group led by Professor Meiling Zhu. I am a Chartered Engineer and worked as an electrical engineer at Sony EMCS(M) Sdn Bhd before obtaining the Zienkiewicz scholarship to pursue my PhD at Swansea University.

I have worked in energy harvesting research since 2014, contributing towards successful project delivery and bidding of grant funding worth over £2M. I have worked on many projects that involved high-value industries such as aerospace, marine and railway with companies such as Airbus, BAE Systems, Babcock and Network Rail. I have generated 3 patents and 30 publications, including book chapters, journal and conference papers in energy harvesting from my research and co-founded a spin-out company Encortec. My research interests include low-power, high-efficiency and adaptive power management circuits for energy harvesting, sensor interfaces and wireless sensor network for industrial monitoring applications.
