Dr. Cathy Lu is a clinical assistant professor of medicine. She completed her internal medicine and gastroenterology residency at the University of Alberta. Dr. Lu completed a joint advanced IBD fellowship with specialization in intestinal ultrasound. She is a member of the STAR (Stenosis, Therapy, and Anti-Fibrotic Research) Consortium executive/operational committee, and IBUS (International Bowel Ultrasound) scientific committee. Her primary research interests are in fibrostenotic Crohn’s disease, intestinal ultrasound, and -omic biomarkers in diagnosis, monitoring, and treatment response in IBD.


Areas of Research

Intestinal Ultrasound and -omic Biomarkers in Crohn's Disease Strictures

My research interests are focused on precision medicine in the diagnosis and treatment of fibrostenotic Crohn's disease (CD), and the use of intestinal ultrasound as a non-invasive, accurate modality to monitor and diagnose CD strictures. In other words, I am studying the use of IUS to diagnose fibrostenotic strictures, combined with identifying biomarkers with basic science collaborators using -omic technology to improve how we predict those who are at risk of developing these narrowings. Furthermore, I am interested in how diet and nutrition play a role in strictures whether as a risk factor, or treatment.
