Hi, I’m

Jiaqing (Allen) Liu

Multimodal AI for Health & Wearable Computing

I’m a second-year PhD student in Computer Science & Engineering at the University of Notre Dame, advised by Tingyu Cheng in the Internet of Matter Lab. My research follows two threads:

  • Multimodal AI for health: foundation models that learn efficient representations from multimodal wearable data, and AI agents that reason over these signals for health monitoring and improvement.
  • Health sensing: turning everyday objects (e.g., clothing) into wearable sensors that capture health signals unobtrusively and continuously in daily life.

Previously, I earned my master’s in ECE at the University of Washington, where I worked with Shirley Xue and Shwetak Patel at the UW Ubicomp Lab on wearable devices and algorithms for low-power, continuous health sensing.
