Dr. Elysa Widjaja is a paediatric neuroradiologist and clinical researcher with expertise in paediatric epilepsy. She leads the pediatric epilepsy neuroimaging for the evaluation of epilepsy surgery at the Hospital for Sick Children. Her research is centred around evaluation of outcomes of epilepsy and its treatments, and improving outcomes of epilepsy surgery.


Widjaja's research focuses on evaluating outcomes of epilepsy and its treatment, including clinical and health-related quality of life outcomes. As well, Widjaja is interested in assessing the health-care costs of epilepsy and evaluating the cost-effectiveness of new epilepsy treatments relative to standard of care treatments. Another area of Widjaja's research is utilizing advanced imaging and image processing to improve outcomes of epilepsy surgery, and to assess brain injury related to recurrent epilepsy.
