Brief Biography

I received my Ph.D. in Clinical Developmental Psychology from York University under the supervision of Jennifer Connolly. I completed Health Psychology post-doctoral training at the Hospital for Sick Children followed by a Fellowship in Clinical Neuropsychology at the Alberta Children’s Hospital.

In April 2010, I took on my current positions at SickKids as the Neuropsychologist with the Pediatric Lupus Clinic and as the Clinical Psychologist with the Haematology Late Effects Clinic. I am very fortunate in both roles to work with interdisciplinary teams of dedicated professionals who strive to advance our understanding of paediatric health conditions and to set standards for quality patient care.
