Xiyun (Eric) Hu

I’m Xiyun Hu, a senior undergraduate at the University of North Carolina at Chapel Hill, double majoring in Computer Science and Statistics with a minor in Neuroscience.

My research broadly focuses on AI and sensing for health, with interests in multimodal and longitudinal data, human-state modeling, trustworthy agentic AI, and personalized digital health systems. I am particularly interested in how AI can reason over heterogeneous evidence from sensing, self-report, clinical data, and human interaction while preserving uncertainty, privacy, and individual differences.

My recent work spans longitudinal behavioral sensing, evidence-grounded AI patient modeling, on-device conversational AI, and multi-agent systems for biomedical research. Across these projects, I am interested in a common question: how can we build AI systems that develop reliable representations of people over time and use them to support meaningful, safe, and personalized decisions?

I am currently preparing to apply for PhD programs for Fall 2027.
