Dr. Williams is currently a neuropsychologist at the Hospital for Sick Children in the division of Neurology. Her current role leads the Neonatal Neuropsychological services for assessment and consultation for children and families following neonatal brain injury and associated medical conditions. Assessments are typically offered prior to school entry and at important academic transition points. Dr. Williams also provides families ongoing consultation and advocacy as needed.

Dr. Williams is currently a Project Investigator with SickKids Research Institute and co-lead of the NeuroOutcomes Lab. Her research focuses on neuropsychological outcomes following early brain injury. She currently is the principle investigator on the Parent Experiences Project. Together with a multi-disciplinary team and a strong group of students and research staff, Dr. William’s research program aims to learn more about modifiable factors promoting resilience following early brain injury, and to identify modes of service delivery that will optimize neuropsychological outcomes.
