Overview

My research expertise lies in machine learning and wearable devices. In particular, I am interested in machine learning for robotics and medicine based on continuous data collected by wearables. Most recently, I have been exploring using foundation models for human health assessment. My research currently has three goals:

(1) develop robust wearable sensors
(2) efficient data processing and model prediction for time-series multimodal biosignals datastream;
(3) advance robotics and health assessment with computationally efficient foundation models.
