I am a Ph.D. student in the School of Computing at The University of Georgia (UGA). I am a member of the MoSIS Lab, under the supervision of Dr. Jian Liu. Before joining UGA, I spent two and a half years in the Min H. Kao Department of Electrical Engineering and Computer Science at The University of Tennessee, Knoxville (UTK), also under the supervision of Dr. Liu.

My research focuses on AI for smart fitness and healthcare. My work leverages mobile sensing, deep learning, and foundation models to model fine-grained human motion and physiological signals.

News

• Oct 2025: One paper has been accepted to Microchimica Acta under Springer Nature.

• Aug 2025: Two papers have been accepted to IMWUT/UbiComp 2025, both focusing on fitness and treadmill-based training.

• Aug 2025: I have moved from UTK to UGA, continuing my Ph.D. studies there.

• Aug 2025: I’m excited to share that I have graduated with a Master of Science in Computer Science from UTK.
