AI for Clinical Decision Support and Health Services
My work in clinical decision support studies how information from patient records and clinical guidelines can inform a clinician’s decision process. The HyCARE research direction combines clinical information extraction with guideline-based decision support, with uncertainty in model outputs examined through evaluation.
I also develop models for health services, including referral networks and emergency-department demand. This work uses network models and time-series forecasting to study how patients move through services and how demand changes over time. C-PATH studies conversational assistance for patient triage.
Causal explanations for graph neural networks provide methods for examining model predictions. Work on medical vision-language representations evaluates image-text retrieval. RELIABLE extends the application scope to population health risk during extreme weather events.
