About

Personal Statement: One of my goals is to ensure swift, consistent and effective treatment is available to anyone who suffers a stroke, no matter where they live in Alberta. In addition to effective treatment, I want to see stroke survivors get the rehabilitation and support they need in order to live their lives to the fullest.

Brian Buck is an Associate Professor in the Division of Neurology and a stroke neurologist at the University of Alberta Hospital, where he treats patients with acute stroke and directs the Stroke Prevention Clinic. He leads the Stroke Program in the Edmonton Corridor and is the current UAH Site Stroke Lead. The Edmonton Stroke Program coordinates stroke care across the Edmonton region and northern Alberta, and provides telestroke consultation to hospitals throughout the province. He trained in vascular neurology at UCLA and the University of Toronto and joined the University of Alberta in 2007. He has served as a site investigator for many of the multicentre trials that have shaped acute stroke care in Canada, including AcT, TEMPO-2 and ESCAPE-NEXT, and was principal investigator of the PER DIEM trial, published in JAMA in 2021, which compared implantable and external cardiac monitoring for the detection of atrial fibrillation after stroke.

Research

Dr. Buck's research addresses two questions: how can stroke be treated faster, and how can a second stroke be prevented? Much of this work concerns the period before patients reach hospital. His group is developing and testing portable tools, including EEG-based devices and point-of-care blood biomarkers, that would allow paramedics to identify large vessel occlusion in the field and route patients directly to the right hospital. A second line of work applies machine learning to electrocardiographic and imaging data to detect hidden atrial fibrillation and to characterize the interaction between the heart and the brain after stroke. A third addresses the organization of stroke care itself: how emergency treatment is delivered, and how systems can be designed so that patients in rural and remote communities receive the same standard of care as those in cities.

This work is conducted through clinical trials and in partnership with paramedics, emergency physicians, and stroke teams across Alberta and Canada. Dr. Buck's research has been supported by the Canadian Institutes of Health Research, the Heart and Stroke Foundation, and Alberta Innovates, and he serves as a peer reviewer for stroke and general medical journals.

He welcomes inquiries from prospective graduate students, residents and fellows interested in stroke, clinical trials, or health systems research.

Teaching

Dr. Buck teaches medical students, neurology residents, and stroke fellows in the clinic and on the wards, and contributes to graduate teaching in stroke and neuroimaging. He supervises graduate students and postdoctoral fellows in clinical stroke research, with an emphasis on trial design, prehospital diagnostics, and the application of machine learning to clinical data.
