Bio

Dr Thornhill completed her M.Sc. and Ph.D. in Medical Biophysics from the University of Western Ontario, where her work focused on cardiac magnetic resonance imaging (MRI). She continued on to do postdoctoral research fellowships at McMaster University and the University of Toronto (Hospital for Sick Children). Since 2010, Dr Thornhill has been working as an Imaging Scientist in the Department of Medical Imaging at The Ottawa Hospital, with special interests in cardiac MRI as well as radiomics and AI in medical imaging. Dr. Thornhill is an Assistant Professor in the Department of Radiology at the University of Ottawa and an Adjunct Research Professor in the Department of Systems and Computer Engineering at Carleton University.

Research Goals and Interests

  • Medical imaging physics, with particular expertise in magnetic resonance imaging and spectroscopy of cardiovascular and metabolic disorders.
  • Radiomics, machine learning, and artificial intelligence in medical imaging, including neuroimaging, oncologic, and cardiovascular applications.
  • Tracer kinetic modelling of dynamic contrast-enhanced magnetic resonance image data.
