dr. simon graham

Dr. Graham is a medical physicist and biomedical engineer with diverse interests in the development of MRI technology for clinical applications involving the brain. In the past, he has conducted numerous studies aimed at improving the understanding of the biophysical properties of biological tissue that affect MRI signal contrast; improving the method and application of functional Magnetic Resonance Imaging (fMRI) of brain activity in healthy individuals as well as patients suffering from stroke, Alzheimer's Disease, mild cognitive impairment, brain cancer, and traumatic brain injury; general development and optimization of MRI methods; and detailed numerical simulations, computational methods, and MRI hardware development towards improved use of MRI and associated medical devices (e.g. deep brain stimulators). He has a lengthy track record of successfully leading collaborative research grants and projects.

dr. eugenie roudaia

Dr. Eugenie Roudaia is a scientific associate at the Rotman Research Institute at Baycrest. The primary aims of her research is to improve our ability to monitor brain health as we age and to identify effective methods to promote optimal perceptual and cognitive function in older adults. To address the first aim, Dr. Roudaia is studying how visual and attentional functions are affected in healthy aging, mild cognitive impairment and Alzheimer's disease and related dementias, using both behavioural measures and electroencephalography (EEG). This research may lead to the development of simple vision-based tests that can assist in the screening or diagnosis of age-related brain disorders, or in the monitoring of brain health. This research will also help us understand how different types of visual functions are affected at different stages of the dementia continuum. To address the second aim, Dr. Roudaia is conducting intervention studies examining the effect of mindfulness meditation on cognition and psychological well-being of older adults. She is also testing whether directly training perceptual abilities can counteract age-related declines in those abilities, and whether it can also improve performance in contexts relevant for daily life.
