She obtained a BSc in Physics (1989) and an MSc in Medical Biophysics (1992) at the University of Toronto, and a PhD from the Robarts Research Institute at the University of Western Ontario, also in Medical Biophysics (1999). Her research covers a wide range of topics in x-ray and CT physics, with an emphasis on image guidance during minimally invasive procedures. She is PI on several NIH-funded projects including 'Real-time Imaging for Transbronchial Needle Biopsy Guidance' and 'kV-MV Imaging for Metal Artifact Reduction in Radiation Therapy Treatment Planning'. Collaborators include researchers from Sydney University and the University of Erlangen-Nurnberg, and from Siemens Medical, Varian Ginzton and TripleRing Inc.
