Valerie Wallace
PhD
Qualification
- BSc University of Ottawa 1987
- PhD University of Toronto 1993
Dr. Valerie Wallace obtained her PhD in the Department of Immunology at the University of Toronto (UT) and completed postdoctoral studies in developmental neuroscience at University College london. From 1998-2013 she was at the Ottawa Hospital Research Institute (University of Ottawa) where she was Senior Scientist and Director of the Vision Research Program. Dr. Wallace joined krembil Research Institute/University Health Network in September 2013, where she is Senior Scientist and Co-Director of the Donald K Johnson Eye Institute and Director of the Vision Science Research Program. She holds appointments in the Departments of Ophthalmology and Vision Sciences and Laboratory Medicine and Pathobiology, University of Toronto. A molecular and developmental biologist by training, she is recognized for her work on the role of Hedgehog signaling in neural progenitor proliferation in the central nervous system. Her lab is now applying this knowledge towards investigating the role of morphogen signaling in tumorigenesis and the development of cell-based approaches for the treatment of blinding eye diseases, including age related macular degeneration.
