I build wearable systems that measure the human body, from custom sensors and circuit boards to signal processing, machine learning and human-subject studies. My research focuses on physiological sensing for health and human-computer interaction, through hardware–software co-design. I am advised by Prof. Xia Zhou in the Mobile X Lab at Columbia University.

Loose clothing was long considered unusable for ECG because the fabric moves with the body. The shirt's own weight and a little sweat hold a thin kirigami sensor to the back, and a hybrid electrode senses motion so it can be filtered out.
92.7% of full waveforms at rest · 84.5% of heartbeats while walking

A portable box that estimates glucose levels from how the palm rotates polarized light, with a light trap that rejects stray reflections. Tested in a 363-day home study with 30 participants, run with the Barbara Davis Center for Diabetes.
Over 95% of predictions clinically accurate or acceptable

Sensors made from conductive fabric and built into everyday textiles: a pillowcase that tracks heart rate, breathing and sleep posture, Joey for kangaroo mother care of newborns, and a fabric sensor for hand-muscle rehabilitation.
My role Built the pillow's sensing prototype, developed Joey's Android app, advised on the hand-muscle sensors
