Behavioral AI, Digital Health, and Agent Systems

Zhiyuan "Ryan" Wang

I am a Ph.D. Candidate at the University of Virginia, where I work on ubiquitous sensing, behavioral AI, and mobile systems for health.

Alongside my academic work, I build AI agent infrastructure: orchestration, tool use, and developer systems for reliable long-running agents. Starting in May 2026, I will join Meta Reality Labs Research as a Research Scientist.

About

Hi! I am Zhiyuan "Ryan" Wang.

I am a Ph.D. Candidate in Systems and Information Engineering at the University of Virginia, advised by Prof. Laura E. Barnes in the Sensing Systems for Health Lab and Link Lab.

Starting May 2026, I will join Meta Reality Labs Research as a Research Scientist, working on Behavioral AI and Proactive Agents for next-generation personal wearables.

My research develops ubiquitous sensing and intervention systems to enhance human health and well-being through interdisciplinary collaborations spanning medicine, nursing, psychology, and bioethics. I also build AI agent infrastructure, systems that make AI agents work reliably at scale.

Previously, I was a Multimodal Behavioral AI Research Scientist Intern at Meta Reality Labs Research (2025) and an AI/ML Data Scientist Intern at Johnson & Johnson Innovative Medicine (2024). I received my B.S. in Computer Science from Xiamen University, China (2021).

Research Keywords: Digital Health, Ubiquitous Computing, Mobile Computing, Human-Centered AI, Behavioral AI, AI Agent Systems
