Biography

Cheryl is an ABGC certified genetic counsellor who completed her Master of Science in Medical genetics at the University of Wisconsin-Madison in 1990. She joined the Department of Genetic Counselling at SickKids in 1991 working within the Division of Clinical and Metabolic Genetics. Cheryl is an Assistant Professor in the Department of Molecular Genetics and clinical supervisor in the MSc Genetic Counselling Program at the University of Toronto. She holds a Project Director appointment at SickKids Research Institute based on her involvement in clinical research and supervision of graduate students. Cheryl has a special interest in 22q11 Deletion Syndrome, overgrowth syndromes, epigenetics and knowledge translation. 

Research

The role of epigenetics in human development as it relates to genetic syndromes is Cheryl’s primary research interest.  Her current research collaborations focus on understanding epigenetic mechanisms and utilizing this knowledge to advance diagnosis, management and potential therapeutic interventions for individuals with conditions resulting from epigenetic dysregulation. 

Cheryl is also interested in 22q11 deletion syndrome (22q11DS) and the development of strategies to enhance the medical and psychosocial management for individuals with 22q11DS.
