Work

The Chronus Health platform, the IBM Research work that preceded it, and what I'm doing now at Twenty Seven Labs.

Case Study

Chronus Health: Whole-Blood Electrical Detection Platform

CBC, CMP, and electrolytes from a single cartridge. No sample prep. No optical detection.

The Challenge

Build a CLIA-waivable point-of-care device for CBC and CMP testing from undiluted whole blood — no sample prep, no optical detection, and a manufacturing path to sub-dollar cartridge COGS.

My Role

Co-founder and CTO. Led the technical vision and a 20+ member cross-functional team across assay development, microfluidics, hardware, and software — from feasibility through IRB-approved clinical studies and FDA pre-submission. Built the internal lab and pilot production infrastructure, directed IP strategy, and led technical due diligence for $28M+ in venture funding.

How It Works

  • 100% electrical detection — no optical components, no sample prep
  • Multiplexed: CBC, CMP, electrolytes, and small molecules from a single cartridge
  • Proprietary aptamer sequences across 13 analyte targets
  • Custom 4-channel lock-in amplifier built in-house at <$2k (vs. $40k+ commercial)
  • Ionophore-doped membranes for direct potentiometric electrolyte read from whole blood

Complete Blood Count (CBC)

Whole-cell impedance spectroscopy

Red blood cells, white blood cells, and platelets measured directly from whole blood with no lysing agents and no optical path. The sensor is a microfabricated microfluidic device on a glass wafer with four parallel measurement paths; the single-use cartridge integrates buffer, mixing, and waste reservoirs alongside the sensor.

Comprehensive Metabolic Panel (CMP)

Aptamer-based amperometric detection

Liver enzymes and proteins detected with proprietary aptamer sequences selected, screened, and validated in-house. Label-free and reagentless — no antibodies, no reagents consumed per test. Thirteen analyte targets form a core IP asset of the platform.

Electrolytes & Small Molecules

Potentiometric ion-selective electrodes

Ionophore-doped PVC membranes miniaturized into a single-use disposable cartridge — the same principle as ISE-based lab analyzers. No enzymatic reagents, no reference electrode consumables, direct read from undiluted capillary or venous whole blood.

IBM T.J. Watson Research Center

2011 – 2017

Developed reactive ion etching processes for next-generation semiconductor devices on 200 mm wafers in the Plasma Physics and Materials Research Labs, and enabled semiconductor–microfluidic integration for molecular-level protein detection on the Exploratory Devices Team. Co-inventor on issued patents covering FET, capacitive, and extended-gate biosensors and selective dry etch for directed self-assembly.

Now: Twenty Seven Labs

Twenty Seven Labs is a diagnostics and biosensor studio working with startups, labs, and investors on assay development, sensor platforms, and diagnostic systems — hands-on bench work combined with system design and strategic guidance.
