Personal homepage

I was born in Brunei and received my B.Eng, MSc. and PhD from University of Glasgow, Scotland. After receiving my bachelor, I worked as a telecommunication engineer at the Department of Telecommunication under the Ministry of Communications of Brunei. In 1998, I returned to Glasgow for my MSc and PhD in RF and photonic technology, especially in the field of photonic integrated circuits and photonic crystal structures. For my post-doctorate, I worked on monolithic microwave integrated circuits, planar RF devices, silicon optical waveguides and semiconductor laser devices. 

I joined the Nano Research group in October 2007 as lecturer in the School of Electronics and Computer Science at the University of Southampton. My current research interests are investigation of semiconductor materials and nanostructures for electronic and photonic integrated circuits. I am also interested in nanofabrication technology and using wafer scale top-down fabrication approach for micro and nanoscale devices.
