About Dr. Trisha Roy

"I am devoted to saving the limbs and lives of patients with vascular disease. As a surgeon-scientist, I am committed to developing and using the most advanced imaging techniques to deliver care that is precisely tailored to the needs of each individual patient."

Dr. Trisha Roy wants to transform the way we plan and perform endovascular procedures with novel imaging techniques. She is a materials engineer, vascular surgeon, wound care physician, and imaging scientist at the Houston Methodist Hospital DeBakey Heart & Vascular Center. She trained at the University of Toronto where she obtained her engineering degree and Doctor of Medicine (MD). She then obtained her PhD through the University of Toronto Vascular Surgeon-Scientist Training Program where she invented a new method to image occlusive peripheral arterial disease using MRI. This patented imaging technique is flow-independent, does not require exogenous contrast, and even has the ability to characterize the morphology and mechanical properties of peripheral arterial lesions.


Dr. Roy is currently an endowed investigator in the Jerold B. Katz Academy of Translational Research. She has been internationally recognized for her research and won international awards including a Vanier scholarship as well as federal grants from the Canadian Institutes of Health Research. She also received a Heart & Stroke Lewar Centre of Excellence Innovation Grant to commercialize her work. After her PhD training, she developed an endovascular steering catheter (CathPilotTM) and co-founded a company with her lab members (Magellan Biomedical Inc.). Dr. Roy currently serves as the Director of Research and Development. Dr. Roy’s clinical focus is limb salvage and she provides the full spectrum of peripheral arterial care including wound care, medical therapy, advanced endovascular treatments, and open surgery. Her ultimate goal is to save limbs and lives by delivering care that is precisely tailored to the needs of each individual patient.
