🧬 Biography

Jiahui Li is a Ph.D. student in Computer Science at the University of Georgia, supervised by Dr. Fei Dou. His research focuses on evidence-grounded and explainable artificial intelligence for clinical diagnosis and health sensing, including multimodal clinical reasoning, physiological time-series modeling, and trustworthy evaluation. His work spans electrocardiography, photoplethysmography, ballistocardiography, bodyseismography, vision-language models, and instruction-tuned large language models.

🔬 Research Experience

Graduate Research Assistant, School of Computing, University of Georgia — Aug. 2024 – Present
Advisor: Dr. Fei Dou

• DynamicDx (Lead): Built a reproducible benchmark of 71 video-grounded neurological consultations across 11 phenomenologies. Evaluation of five vision-language models localized the primary diagnostic bottleneck to evidence acquisition rather than downstream interpretation.
• EarlyDx (Lead): Designed an admission-anchored benchmark for open-ended, evidence-supported emergency-department diagnosis, testing whether generated diagnoses are grounded in retrievable clinical evidence.
• DeepArrhythmia (Lead): Developed segment-contextualized electrocardiogram classification with selective acquisition of waveform images, R-peak locations, and rhythm-morphology evidence, producing an auditable decision trace.
• BEACON-BP (Lead): Studied contactless blood-pressure estimation from bed-frame geophone sensing using invasive arterial-line measurements as the clinical reference.
• Peak-Detector / Peak-R1 (Lead): Built instruction-tuned large-language-model methods for explainable peak detection across ECG, PPG, BCG, and BSG without per-modality retraining.
• ADLGen (Co-Lead, co-first author): Synthesized symbolic, event-triggered smart-home sensor sequences for activity modeling and ambient assisted living.

Research Assistant, Hong Kong University of Science and Technology — 2023 – 2024
Supervisor: Prof. Dit-Yan Yeung

• Built MGTST, a multi-scale, cross-channel gated Transformer for multivariate long-term forecasting in high-dimensional time series.
