Micro-electronics research engineer with experience in design and test of full-custom CMOS integrated circuits, special interest in Optical Systems, Laser Ultrasound Systems

Current Research

I am currently working on a novel temporal pixel multiplexing camera. At the heart of it is a novel CMOS chip - the TPM. It offers a novel way of capturing images in low light a a very high frame rate, with user-customizable frame interleaving. The chip has been manufactured and is under rigorous characterization now. I'm working with Roger on this project.

I also work on the use of a novel laser ultrasound detector, the Speckle Knife Edge Detector (SKED). I recently spent a year characterizing it and investigating its feasibility for field work. The SKED is currently under test as a suitable detector in a SRAS system, especially for components with rough surfaces. I'm working with Rikesh, Roger and Steve on this project.
