Xi Bai

Xi Bai serves as a Senior Research Fellow, Health Data Scientist, and Product Engineer at the UCL Institute of Health Informatics, University College London, with an additional Honorary Researcher position at University College London Hospitals NHS Foundation Trust since August 2021. His academic foundation includes a Ph.D. in Artificial Intelligence and its Applications from the University of Edinburgh and an M.Sc. in Computer Software and Theory from Jilin University.

His research centers on Natural Language Processing for clinical applications, specifically developing NLP models for clinical coding and de-identification of Electronic Health Records, alongside building scalable integration systems for wearable/mobile health data collection. His work spans mHealth, MLOps, and speech technology, directly advancing UN Sustainable Development Goal 3 (Good Health and Well-being) through digital health innovation.

His publication trajectory (2021-2025) reveals three dominant research thrusts: (1) NLP systems for clinical text processing (e.g., MiADE, otology symptom extraction), (2) wearable-based remote disease monitoring (SARS-CoV-2 detection, long COVID analysis), and (3) real-world healthcare IT deployment (CogStack platform). These works demonstrate consistent interdisciplinary collaboration across computer science, clinical medicine, and public health domains.
