About

Research Overview

I am a researcher working at the intersection of health informatics, machine learning, and epidemiology. My primary focus is on developing intelligent systems for predictive health management — particularly fall risk assessment and geriatric care — through multimodal deep learning and wearable sensor fusion.

With a clinical background in preventive medicine from Sun Yat-sen University and ongoing graduate training in health informatics at Karolinska Institutet & Stockholm University, I bridge the gap between data-driven AI and real-world clinical applications.

My published work includes transformer architectures for skeleton-based fall prediction, multimodal IMU-image fusion networks, global disease burden analysis using GBD data, and graph neural networks for epidemiological nowcasting. I have served as Principal Investigator on a nationally-funded research project on gait-based risk identification in the elderly.

AI-Driven Fall Risk Prediction & Elderly Care

Sun Yat-sen University School of Public Health (Shenzhen) · A.P. Yang Zhao Research Group

PI & Team Member

Developed predictive models for personalized health management and elderly care using machine learning and deep learning. Concentrated on sensor-based health monitoring — integrating motion recognition technologies, spectral analysis (FFT/GAF), and spatial-temporal skeletal transformers (MSS-Former) — for early detection and risk stratification of geriatric fall risk. This work produced 5 peer-reviewed publications including in Neural Networks (IF 6.3) and IEEE IoT Journal (IF 10.6).

Gait Anomaly Analysis & Intelligent Fall Intervention

Innovation & Entrepreneurship Training Program 2023 · Shenzhen Medical Research Fund (A2301041)

Project Leader / Principal Investigator

Led the development of a real-time gait risk identification model for elderly individuals using inertial measurement units (IMU). Applied Gramian Angular Field (GAF) image encoding and multi-branch ResNet architecture to convert 6-axis IMU signals into RGB feature images for fall prediction. The innovation project received the highest school review rating of "Excellent". The subsequent national grant (¥50,000, SMRF) extended this work into an intelligent intervention system combining large deep learning models with deep imaging data.
