Dr Gillian Blue is a Postdoctoral Researcher and Genetic Counsellor at the Heart Centre for Children, The Children’s Hospital at Westmead. She is a Clinical Senior Lecturer at the Discipline of Genetic Medicine, The University of Sydney and a Visiting Scientist at the Victor Chang Cardiac Research Institute. She has a broad range of skills and experience including clinical, basic science and psychosocial research. Her primary research interest and track record is understanding the genetic mechanisms underlying congenital heart disease (CHD) using genomic technologies, and this is combined with an equally thorough understanding and track record in associated clinical and psychosocial implications. During her National Heart Foundation of Australia Postdoctoral Fellowship, she investigated genetic burden and how this contributes towards disease severity and variable expression. She is an Australian Genomics Cardiovascular Flagship Site Lead and together with a colleague, leads the CHD program. In 2019, she established Australia’s first genetics clinic dedicated to patients and families with CHD to facilitate direct translation of genetic findings into patient care and clinical management. She also manages the Kids Heart BioBank, the largest resource of its kind in Australia, and key to facilitating genetic research in CHD.
