Spotlight
Like all electrical engineering undergraduates, Sri Krishnan was in search of a topic for his fourth-year capstone project. That’s when he got the call that would set the trajectory of his career. His uncle had suffered a heart attack. Krishnan went to the hospital to find his uncle hooked up to heart monitors plotting ECG signals. The waveforms were familiar to Krishnan. They looked the same as the mathematical waves seen in his engineering textbooks. It triggered an idea: Why not apply those mathematical ideas to understanding heart rhythm?
The capstone then led to graduate focus on biomedicine, with Krishnan developing low-cost, non-invasive screening devices for orthopedic surgeons treating knee injuries. He has since returned to cardiovascular applications, beginning with a Toronto General Hospital collaboration that looked into understanding sudden cardiac death. But don’t call Krishnan a biomedical engineer. He has dedicated his career to breaking down silos within engineering through the interdisciplinary study of electrical, computer and biomedical fields. “In an ideal world, engineers would have real interdisciplinary knowledge,” says Krishnan. “That is how students will make an impact going forward.”
