Dr. Sylvie Langlois is a Clinical and Molecular Geneticist and Emeritus Professor in the Department of Medical Genetics at UBC. She was a clinical geneticist in the Provincial Medical Genetics Program at C&W for over 30 years.

She implemented the BC Prenatal Genetic Screening Program in 2009 and remains its Medical Director to this date.

As a clinician scientist, her research contributions have been in the areas of molecular genetics and prenatal screening. Her research was always inspired by the patients she cared for and has focused on the implementation of new technologies to improve patient care.

Most notably, she was the co-Principal Investigator, alongside Dr. François Rousseau, of two Genome Canada-funded projects that investigated the use of cfDNA in maternal plasma to screen for fetal chromosomal aneuploidy.
