Justin Xu
PhD Candidate
Justin joined the Big Data Institute in 2023 as a PhD Candidate in Biomedical Data Science. His research aims to leverage AI to decipher clinical data and enhance healthcare. Specifically, his current doctoral work focuses on developing, deploying, and evaluating AI tools to help hospitals manage patient demand. Justin is co-advised by David Eyre, Sarah Walker, and David Clifton. He is principally funded by Oxford University Press via the Clarendon Fund Scholarship.
In 2024, Justin visited Stanford University as a Canadian Fulbrighter and joined the Centre for Artificial Intelligence in Medicine & Imaging (AIMI) under Curtis Langlotz. He is developing multimodal generative AI in radiology, including interpretive LLM-based metrics for clinical report generation and vision-language systems capable of understanding temporal relationships in medical images.
Prior to Oxford, Justin worked with Alistair Johnson at the Hospital for Sick Children in Canada. During this time, he worked with the MIMIC-IV dataset and deployed a clinical terminology annotation dashboard with NLP to support multi-site analyses of EHRs. Additionally, under Matthew McDermott, he developed the “Automatic Cohort Extraction System for Event-Streams (ACES)” and contributed to the “MEDS Dynamic Extensible Validation (MEDS-DEV)” benchmark for medical time series representation learning. Justin was trained as a biomedical engineer and holds a BASc in Engineering Science from the University of Toronto.
