Biography:

Born in Winnipeg, Manitoba. 

High school in Toronto.

Life Sciences degree at Queen’s and Medical school in Winnipeg.

Happily married with 2 dependent golden retrievers and a child. 

Awards:

2005:  Received the Best Scientific Poster Award at the Canadian Association Radiologists Meeting (Sept 29-Oct 2, 2005) for my research optimizing CT scout technique.

2005:  Awarded the Canadian Society for Clinical Investigation and Canadian Institutes of Health Research (CSCI/CIHR) Resident Research Award for the University of Saskatchewan for my helical HRCT radiation dose research.

Research Interests:

Main research interest is radiation dose and methods of reducing radiation exposure to radiosensitive organs from diagnostic imaging.

Other projects currently include:

  Investigating positional induction of sterno-clavicular joint pneumatosis in CT.

  Investigating MRI bone marrow signal changes following Uterine Artery Embolization.
