Research Positions

Head of Cardiovascular Research, The Hospital for Sick Children (SickKids)
Senior Scientist, SickKids Research Institute


Dr. Seema Mital completed her paediatric residency at Children’s Hospital of Michigan in 1996 and a fellowship in Paediatric Cardiology in 1999 from Columbia University, New York, USA. Mital was Assistant Professor at Columbia University, Morgan-Stanley Children’s Hospital of New York, until 2007 when she joined SickKids as a staff cardiologist in the Heart Function and Transplant Program.

Mital serves on the executive committees of the SickKids Labatt Family Heart Centre, the Heart and Stroke Richard Lewar Centre of Excellence, the Ted Rogers Centre for Heart Research, and the Canadian Heart Function Alliance. She is also a fellow of the American Heart Association and serves on the Scientific Publications Committee, as well as the Strategic Outcomes Committee.


Mital leads the Cardiac Precision Medicine Program of the Ted Rogers Centre for Heart Research at SickKids. Her research in cardiac precision medicine leverages genomics, stem cells, AI and digital technology to model disease, test therapies, and implement precision-focussed decision support tools. Mital established the SickKids Heart Centre Biobank, a multi-centre biorepository for childhood onset heart disease, one of the largest international repositories of its kind. Mital leads the ERAPerMed/CIHR funded PROCEED network for Personalized Genomics in congenital heart disease, leads the multi-centre international Precision Medicine in Cardiomyopathy (PRIMACY) network, as well as the CIHR-funded INSERT-HCM study.
