About
Integration across disciplines is the through-line of my work
Engineering executive, hardware platforms. Twenty years synthesizing chemical engineering, electrical engineering, mechanical engineering, physics, and chemistry into shipping systems: silicon-photonic biosensors at Evanostics, dissolving microneedles at Corium, a needle-free injector that won the Edison Silver Medal.
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) for the 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.
Programs
The three programs below are the through-lines of the work. Each links to a fuller technology journey.
Evanostics: Silicon-Photonics Biosensor Program from Concept to Clinical Stage
A saliva-based diagnostic platform built across four converging workstreams: photonics and chip fabrication, the 10-plex competitive immunoassay, modular fluidics with the oral-fluid collection device, and a clinical-grade reader. Reached clinical validation. Eight granted US patents. Read the journey.
Corium MicroCor: Dissolving Microneedle Patch
A dissolvable microneedle patch for transdermal delivery of biologic drugs, in a wearable patch form factor. Six granted US patents across three engineering disciplines: microfabrication for the silicon master and needle array; surface physics and chemistry for void-free fill of the micro-cavity and the drying physics that followed; mechanical engineering for the applicator and impact mechanics. Phase 1 and Phase 1A clinical trials. Contributed to Corium’s IPO. Read the journey.
Corium MicroJet: Piezo-Driven, Needle-Free Injector
A piezo-driven, electronically controlled needle-free injector in a wearable patch-pump form factor. Recipient of the Edison Silver Medal, Game Changer in Medical Technology (2010).
