Brief profile

My research interests are the modelling, simulation, and optimisation of very large scale integrated (VLSI) circuits. The breadth of my engineering background and my foundation in electronic engineering has allowed me to pursue research topics across several areas, such as ASIC power management, Radio Frequency (RF)/telecommunications and recently the detector ASIC. My research field in power management for ASIC resulted in various analysis and circuit implementations of voltage supply scaling and leakage current reduction techniques to address the current issues in dynamic and static power dissipation.

The current research involves in the design of 5.8GHz RFID.
