Dr. Janet Rossant is a Senior Scientist in the Developmental & Stem Cell Biology Program and Chief of Research at The Hospital for Sick Children, Toronto. She is also a University Professor, University of Toronto, and Professor in the Departments of Molecular Genetics, Obstetrics/Gynaecology and Paediatrics, University of Toronto. Her research interests centre on understanding the genetic control of normal and abnormal development in the early mouse embryo using both cellular and genetic manipulation techniques. Her interests in the early embryo have led to the discovery of a novel placental stem cell type, the trophoblast stem cell. She is Deputy Scientific Director of the Canadian Stem Cell Network.
Dr. Rossant trained at the Universities of Oxford and Cambridge, United Kingdom and has been in Canada since 1977, first at Brock University and then at the Samuel Lunenfeld Research Institute, Mount Sinai Hospital, Toronto, from 1985 to 2005. Dr. Rossant has been recognized for her contributions to science with many awards, including the Killam Prize for Health Sciences, the March of Dimes Prize in Developmental Biology, the Conklin Medal from the Society for Developmental Biology, and the CIHR Michael Smith Prize in Health Research, Canada’s most prestigious health research award. She is a Fellow of both the Royal Societies of London and Canada, and is a foreign Associate of the US National Academy of Science. She was most recently recognized in June, 2013, with the Ross G. Harrison Medal (lifetime achievement award) from the International Society of Developmental Biologists.
Dr. Rossant is actively involved in the international developmental and stem cell biology communities. Dr. Rossant has contributed to the scientific and ethical discussion on public issues related to stem cell research. She chaired the working group of the Canadian Institutes of Health Research on Stem Cell Research, which came up with guidelines for CIHR funded research in this area.
