Research snapshot

How reliably can ordinary cameras recover physiological signals outside controlled settings?

I work on robust remote PPG, non-contact stress estimation, egocentric vision, and medical image analysis.

01 / RESEARCH

Research focus

My research combines computer vision, biosignal processing, and deep learning to measure physiological signals without physical contact.

Current projects cover robust remote photoplethysmography (rPPG), stress estimation, and heart-rate estimation from egocentric NIR eye video. My earlier work includes maxillary-sinus segmentation in panoramic X-rays and knowledge distillation for semantic segmentation.

Long term, I am interested in physiological sensing with egocentric and wearable cameras.
