Human-centered AI · Ubiquitous computing · Multimodal sensing

I build intelligent systems that understand human behavior beyond the lab.

I’m a Computer Science Ph.D. student at Georgia Tech, advised by Prof. Thomas Plötz. My work combines generative AI, embodied agents, and multimodal sensing to create scalable, privacy-conscious tools for understanding activity, engagement, and behavior.

From simulated worlds to real human moments

I develop methods that make human-centered sensing more capable and more practical: generating virtual sensor data when real data is scarce, learning from physiological and behavioral signals, and designing systems that work across people, environments, and modalities.

01

Generative sensing

LLMs and embodied agents generate diverse, privacy-preserving motion and ambient sensor data for human activity recognition.

Multimodal understanding

Wearable, physiological, visual, and interaction signals reveal engagement and behavior in realistic settings.

Inclusive human-centered AI

Data and models designed around real people—including accessibility and health contexts—rather than idealized benchmarks.
