Jiaying Ye

I am an undergraduate student at the University of Washington , studying Applied Mathematics–Data Science and Informatics.

My research interests lie at the intersection of machine learning, wearable sensing, physiological signal processing, and mathematical AI.

I currently work with the Ubicomp Lab and Math AI Lab at the University of Washington, where I study wearable physiological sensing and representation learning for mathematical reasoning.
