Professor, Systems Design Engineering; University Research Chair

Research interests: Imaging Devices, Micro/Nanodevices, MEMS; Nanosensors


As Canada Research Chair in Micro and Nanodevices, Professor John T.W. Yeow is developing nanodevices (machines that work on a molecular level) and highly selective sensors that will help create new medical instruments for diagnosing and treating disease.

Bringing together knowledge and technology from chemistry and from materials and chemical engineering labs, Yeow will design, develop, manufacture, and test a miniaturized catheter device for in vivo, or internal, body imaging. This device will allow physicians to examine small and previously unseen human cavities, and assist in the early detection of diseases such as cancer.

Yeow is also developing miniature radiation instruments and sensors for cancer treatment that will allow for a more focused, yet less invasive, delivery of radiation treatment, as well as real-time measurement of the delivered dose during radiation therapy.

Ultimately, Yeow’s research will improve patients’ quality-of-life through the early detection of disease and the development of more effective treatment. In this translational research, the technologies developed will find applications in areas beyond biomedical applications.
