About me
Doctor of Philosophy
I am a GaN Technology specialist with expertise in RF and Power devices and systems. My core strengths lie in Process Integration (70–250 nm) and GaN HEMTs on Si/SiC/Diamond-based device design, fabrication, and characterization. With more than 70 international publications, I have established deep technical proficiency as a Wide-bandgap Semiconductor Technologist.
I previously served as a Senior Scientist at IME A*STAR, Singapore, and have extensive experience in GaN-on-Si/SiC/Diamond technologies. Prior to this, I worked as a Scientist at DRDO. I hold a PhD from NTU Singapore.
