Portable Urianalysis

Developed for UC San Diego Health in collaboration with Rady Children’s Hospital

A portable point-of-care urinalysis device that performs spectral analysis of reagent-treated urine samples to quantify biomarkers including pH, nitrite, nitrate, and creatinine. The system captures wavelength-specific reflectance data and converts it into calibrated concentration estimates within a compact, battery-powered enclosure.

My impact

  • Co-led the mechanical and system-level architecture, from concept to validated prototype

  • Designed a light-controlled optical measurement chamber to ensure consistent spectral readings and reduce environmental noise

  • Integrated multi-channel spectral sensors, reagent interface, and embedded electronics into a manufacturable enclosure

  • Developed calibration workflows to translate spectral data into quantitative biomarker estimates

  • Iterated tolerances, materials, and power architecture to improve measurement repeatability and device robustness
