MD, FRCPC
Research Synopsis
Dr. Halliday is a clinically oriented Neuropathologist with a longstanding interest in correlative studies, particularly clinical-pathological and radiological-pathological correlations. Expertise with morphological investigations is shared with collaborative research studies, especially in the area of oncology (retinoblastoma). Central nervous system traumatic injury, particularly as it relates to infants, is an ongoing interest.
