About

Twenty years across silicon photonics, sensing systems, and microfabrication.

I take technology platforms from concept to pilot line. Twenty years across silicon photonics, sensing systems, and microfabrication.

Innovation by synthesis across chemical engineering, electrical engineering, mechanical engineering, physics, and chemistry.

Silicon photonic biosensors. Dissolvable microneedle drug delivery. Surface physics for microfluidic control. Cleanroom commissioning, anisotropic silicon etch, and microfabricated single-cell electroporation at IIT Bombay (in partnership with the Cancer Research Institute Mumbai).

Sixteen granted US patents (six at Corium, eight at Evanostics, two at the University of Washington), more than fifteen peer-reviewed publications cited 500+ times, including a Langmuir paper at 400+ citations and an Advanced Materials cover article. Edison Silver Medal: Game Changer in Medical Technology (2010, Corium MicroJet needle-free injector).

The wearable form factor is a thread through most of this work. Wearable patch pumps and dissolving microneedle patches at Corium. A silicon-photonics biosensor at Evanostics whose core action lived on a 3-by-3 mm chip; silicon-photonics biosensing later compressed into a wearable at SiPhox. Progressive integration is the through-line that turns instruments into wearables.

The full career is on the CV. Longer treatments of the work are under Technology Journeys and Writing.
