Brief Biography

Dr. Freda Miller is a cell and molecular developmental neurobiologist at The Hospital for Sick Children Research Institute and Professor at the University of Toronto.  She is a Howard Hughes Medical Institute International Research Scholar, Canada Research Chair in Developmental Neurobiology, a Fellow of the Royal Society of Canada and a Fellow of the American Association for the Advancement of Science.  She has authored more than 140 scientific papers, reviews and book chapters and has 15 patents (issued and pending).  

Dr. Miller is best known for her studies of neural and dermal stem cells and of neuronal growth, survival and apoptosis.  Major findings from her lab have provided evidence that adult mammalian skin contains an accessible multipotent dermal stem cell that can generate peripheral neural cells, that the p75 and p63 play a critical role in determining the life, death and degeneration of mammalian neurons, and that one way genetic disorders cause cognitive dysfunction  is by perturbing embryonic neurogenesis.

Dr. Miller obtained her B.Sc. in Biochemistry at the University of Saskatchewan, her PhD in Medical Sciences from the University of Calgary and completed her postdoctoral training at the Scripps Research Foundation.  She then held faculty positions at the University of Alberta and the Montreal Neurological Institute at McGill University prior to moving to her current position in 2002.  Dr.  Miller was also a founder of Aegera Therapeutics Inc., a Canadian biotechnology company. 

Research Interests

  • Neurotrophin regulation of neuronal survival, growth and connectivity
  • Role of p53 family in the nervous system
  • Molecular regulation of neurogenesis

Research Activities

During embryonic development the nervous system is confronted with a problem of enormous complexity; to progress from a thin sheet of neuroepithelial cells to a network of neuronal circuitry that is able to process sensory information and generate an appropriate motor output. One of the ways that the mammalian nervous system achieves this end point is by overproducing both neurons and neuronal connections, and then eliminating those cells and/or connections that are not appropriate. However, this is not something that is limited to the developing nervous system. Many of the same cellular mechanisms remain "in place" in adult animals, thereby allowing structural and/or functional remodeling in response to physiological stimuli, and providing repair mechanisms for the injured and traumatized mature nervous system.

These complex developmental processes are determined by an intimate interplay between intrinsic cellular programs and environmental cues. Within this broad context, my laboratory is interested in understanding how growth factors and neural activity regulate the genesis, survival and growth of developing neurons and regulate the establishment of appropriate neuronal connectivity.
