About

I am an incoming PhD student in Computer Science at Florida State University, Intructed by Dr. Yang Liu. My current research interests center on wearable devices, mobile sensing, human-computer interaction, and edge AI.

Before beginning my PhD, I worked on machine learning applications across several domains. These past projects form my broader research background, while my doctoral work focuses on building intelligent, useful, and respectful technologies for people.

Current Research

Wearable Sensing

Developing sensing systems that understand human context while remaining practical and unobtrusive.

Human-Centered AI

Designing intelligent systems around real human needs, limitations, privacy, and trust.

Mobile & Edge Computing

Exploring efficient models and interaction techniques for everyday devices and on-device intelligence.
