From a very young age, Karthi Umapathy wanted to know things were made and how they functioned. “I would often disassemble my toys out of curiosity, much to the dismay of my parents,” says Umapathy. “This curiosity and my affinity to create or improvise things organically pushed me towards engineering.”

That insatiable curiosity led him to biomedical engineering, a field that is an  integral part of health care. In his collaborative research with major hospitals in Toronto, he uses advanced signal and image processing solutions, magnetic resonance imaging (MRI) methods and computational modelling to arrive at practical solutions to challenging medical problems. 

Given Umapathy’s own journey into engineering, it’s not too surprising that as a professor he always tries to instil a deep sense of curiosity into his students. “At the university level, teaching learners to independently seek, understand and apply the knowledge is critical towards their lifelong learning,” says Umapathy. “Open-ended probing with guidance leads them to discover their own passions.”

Professor Karthi Umapathy poses near a window in the George Vari Engineering and Computing Centre.

“Solving real world biomedical engineering problems is a fulfilling experience because it has a direct, positive impact on the health of our society.”
