I use MRI scanners to image the human brain. Since these scanners don't use radiation like CT scanners or X-ray machines, we can scan people – even babies – multiple times. My main research focus is to develop and use new methods to get sharper images and detailed maps of the brain.
I use these techniques for the diagnosis and investigation of concussion, for instance. We have scanned young ice hockey players before and after concussion and we were able to measure the changes in their brains due to concussion.
We also investigate what happens to the MRI signal when the myelin in the brain is damaged. Myelin is the insulator around the nerve fibres. Damage to the myelin due to injury or disease leads to impairment of the brain and has serious consequences for patients. We develop MRI methods for the measurement of myelin damage and repair. These methods allow earlier and better diagnoses of diseases and help medical doctors to initiate the right treatment as early as possible.
