Brief Biography

Dr. Norman Rosenblum is a paediatric nephrologist and senior scientist at The Hospital for Sick Children (Sickkids) and the Sickkids Research Institute.  

He is an MD graduate of Dalhousie University. He completed his paediatric residency and fellowship in paediatric nephrology at the Children’s Hospital, Boston followed by a post-doctoral fellowship in the laboratory of Dr. Bjorn Olsen in the Department of Anatomy and Cell Biology, Harvard Medical School.  He has received support for his research via grants from the Kidney Foundation of Canada and the Canadian Institutes of Health Research.  He is also the recipient of a Canada Research Chair, Tier 1 in Developmental Nephrology.  

Dr. Rosenblum is deeply engaged in developing and managing career development programs for clinician-scientists. He founded and led the Canadian Child Health Clinician Scientist Program from 2001-2012. From 2009-2017, he served as Associate Dean, Physician Scientist Training in the Faculty of Medicine at the University of Toronto. 

He is a professor of paediatrics, physiology, laboratory medicine and pathobiology in the Faculty of Medicine at the University of Toronto, and is currently the scientific director of the CIHR Institute of Nutrition, Metabolism and Diabetes.

Research Interests

  • Kidney development
  • Branching morphogenesis and nephrogenesis
  • Lineage tracing and cell fate
  • Ex vivo and in vivo disease modeling
  • Congenital kidney-urinary tract malformation
  • Growth factor signaling

Research Activities

The major research focus in Dr. Rosenblum’s lab is the investigation into the molecular and cellular mechanisms that control renal development in humans and animal models. His lab aims to answer the following questions:

  • How is formation of the kidney accomplished?
  • What are the cellular and molecular mechanisms underlying malformation?
  • How can we use human genetics and experimental nephrology to inform our understanding of kidney development and human disease?

His laboratory is investigating the functions of signaling pathways controlled by sonic hedgehog, integrin-linked kinase and transforming growth factor β proteins during normal kidney formation and in renal malformation. Work resulting from these endeavours has demonstrated distinct functions for these effectors in controlling renal branching morphogenesis and nephron formation.

Research in the Rosenblum lab also focuses on renal disease modeling using various complimentary experimental models. One such example is the use of human kidney organoids derived from induced pluripotent stem cells (iPSCs).
