about me

Hi! I'm ilina, a bioengineering grad (Dec 2025). I like building things that solve real problems, whether that's in a cleanroom or a code editor.

I'm also secretary of InspireAbilities, a 501(c)(3) nonprofit supporting families of kids and adults with disabilities — something close to my heart. 🌸 Outside of work: making tiny weird tech things, decorating planners, and reading.

🩺 FDA MAUDE Explorer
Companion to the Recall Explorer, built for the FDA MAUDE database — patient injury, malfunction, and death reports rather than regulatory recalls. Uses TF-IDF + NMF topic modeling on free-text narratives to surface common failure themes (e.g. "software alarm", "catheter fracture", "battery failure") without a fixed keyword list.

🏥 FDA Device Recall Explorer
Streamlit dashboard for exploring 37,000+ FDA medical device recall records pulled live from the openFDA API. Filterable by classification (Class I/II/III), manufacturer, date range, and failure mode keyword — with trend charts, manufacturer breakdown, keyword frequency analysis, a US state map, and CSV export.

🥾 Boot Sense — Smart Rehab Boot
Senior capstone project: a smart rehabilitation boot using embedded load cells and haptic feedback to alert patients when they exceed prescribed weight-bearing limits during recovery. Hysteresis-based firmware (triggers at ≥30% body weight, resets at ≤20%) prevents false positives from normal weight shifting.

📊 Physician Stress & Patient Safety — UT + Johns Hopkins
Undergraduate research studying the relationship between physician stress and patient safety. Built Python and MATLAB pipelines to process physiological data collected from anesthesiology residents during clinical rotations. Findings suggested elevated resting heart rate correlated with near-miss events independent of self-reported stress scores. Code available on request (patient data is HIPAA-protected).
