After a person has a stroke, every minute counts. Katie Lin spends her days making sure that the first health-care worker to care for someone who has had a stroke knows exactly what to do. “My work is measured in minutes and lives saved,” she says.
Lin is the first doctor in Canada to be certified in both emergency and stroke medicine. Her dual certification allows her to bridge both fields, integrating advanced stroke care directly into emergency medicine.
She’s also an accomplished educator who trains health-care providers in neurocritical care — a specialty focused on saving lives and preserving brain function in people with life-threatening brain conditions like strokes and traumatic injuries. In 2025, she developed SYNAPSE, a training program that’s been used to teach more than 1,000 doctors, nurses and EMTs around the world.
Lin immigrated to Canada from China with her family when she was a toddler. When she was still in elementary school, her grandmother had a stroke. Her grandmother survived, but was physically and mentally changed.
That inspired Lin to study neuroscience at Queen’s, followed by medical school at UCalgary, where she fell in love with emergency medicine. “It’s this beautifully choreographed dance of clinical expertise where you’re doing all the right things that you need to be doing in the moment you need to do them, and you end up saving a life,” she says.
Lin works at the Foothills Medical Centre and Rockview General Hospital, and as a STARS Air Ambulance critical-care physician. She thrives on the adrenaline of pulling together as a team to save a life. “There’s just nothing like that feeling, and it’s what keeps me coming back to this job every time,” she says.
