  • FRCPC, 1994
  • MD, University of Toronto, 1990

Interests

Research Focus

The major focus of Dr. Nowaczyk’s research is genetic disorders both at the basic sciences and clinical level. Her greatest scientific contributions lie in the area of Smith-Lemli-Opitz syndrome, and new syndrome delineation where she is recognized as an expert internationally. She has participated in paradigm-shifting gene discovery of Cornelia de Lange syndrome, Floating-Harbor syndrome and encephalocranio-cutaneous lipomatosis.

Her other research endeavors relate to the way in which narratives shape the lives of patients and the patient-doctor interactions – a field called narrative medicine.

She is currently pursuing a Master’s of Fine Arts degree in creative writing at University of British Columbia.

Clinical Focus

Dr. Nowaczyk spends most of her professional time in the area of clinical genetics providing inpatient consultations to pediatric wards and the neonatal intensive care units, and of prenatal genetics where she provides consultations for both known and emergent genetic conditions.

Academic Interests

Dr. Nowaczyk teaches undergraduate students in the Bachelor of Health Sciences Program, medical students, and post-graduate trainees in the pathology, paediatrics and obstetrics-gynaecology residency programs. She is the program director of the McMaster site of the Canadian College of Medical Geneticist training program where she supervises fellows both in the laboratory and clinical subspecialties.
