Previous Education/ Experience: I pursued undergraduate studies in Physics at Queen’s University in Kingston and received my PhD in Medical Biophysics from the University of Toronto in 1990. I went on to work as a Research Associate and Assistant Scientist at the University of Wisconsin where I earned a National Cancer Institute FIRST award. Moving to Carleton University in Ottawa in 1995, I helped establish the Ottawa Medical Physics Institute and pioneered hyperpolarized xenon-129 for lung MRI in rodents. In 2004, I joined the Robarts Research Institute (RRI) where I held a CIHR Industry-Partnered Chair award for Respiratory Imaging as the Director of the Robarts GE 3T MRI Facility. The RRI team produced the first xenon-129 human lung images in Canada and the first carbon-13 lung images in the world. In 2013, I joined SickKids as a Senior Scientist where I am focusing on MRI approaches to study the lungs of children and young adults.
Current research interests: My current research involves hyperpolarized xenon-129 and proton MRI of anatomical and functional lung tissue and cellular biomarkers, specifically: airway and lung parenchymal morphology, ventilation, perfusion, gas exchange and inflammatory cell trafficking in lung diseases afflicting children and animal models of these diseases.
