AI Specialist | Data Scientist | Neurodegenerative Disease Research

Hello! I’m Ying Xu (Fiona), currently a Data Scientist at Washington University in St. Louis School of Medicine. I received my Master of Science in Computer Science from WashU and have more than eight years of experience in artificial intelligence.

🔬 Research Domains

• AI for Medicine — Nature Medicine 2026, Nature Medicine 2025, Nature Aging 2025, Alzheimer’s and Dementia 2026, Neuron 2026
• Large Language Models (LLMs) — DMKD 2024
• Graph Neural Networks (GNNs) — AAAI 2024
• Deep Reinforcement Learning (DRL) — ICMLA 2024
• Trustworthy AI — AAAI 2024

Building on my earlier research in GNNs, DRL, LLMs, and trustworthy AI, I have expanded my work toward AI-driven biomedical discovery and translational medicine. My current research focuses on developing machine learning, deep learning, and multi-agent AI frameworks for neurodegenerative disease diagnosis, biomarker discovery, disease co-pathology analysis, and large-scale proteomics-based precision medicine.
