Rebecca Feldman

RebeccaRebecca Feldman’s research focus is on the development of high-field magnetic resonance imaging and magnetic resonance spectroscopy pulse sequences. Her goal is to use these technical developments to unlock the potential of 7T MRI to examine the structures of the human brain in extraordinary detail. In her spare time, Rebecca adapts 7T MR images into beautiful representations of the brain. Prior to joining Dr. Balchandani at TMII, Rebecca worked developing 23Na-MRI sequences at the University of Alberta. She has an MSc and PhD in Medical Biophysics from the University of Western Ontario, and a BASc in Engineering Science (Electrical) from the University of Toronto in Canada.
