Research Positions

Scientist, Developmental and Stem Cell Biology

U of T Positions

  • Associate Professor, Department of Surgery
  • Associate Member, Institute of Medical Science


Dr. Zani received his MD and completed his paediatric surgical training at Sapienza University of Rome, Italy. He earned his PhD from University College London, U.K., investigating stem cell therapy in necrotizing enterocolitis. Following this period, he advanced his clinical training in the U.K. by working in renowned teaching institutions like Great Ormond Street Hospital and King’s College Hospital, London, where he focused on neonatal and paediatric surgery. He then moved to Toronto for a fellowship in neonatal surgery. In 2016 he joined SickKids as a Staff Surgeon in the Division of General and Thoracic Surgery and Scientist-Track Investigator in the Developmental and Stem Cell Biology program at SickKids Research Institute. 


Dr. Zani has two main areas of research interest:

  1. Basic science research in fetal and neonatal surgical conditions that are burdened by high morbidity and mortality rates, such ascongenital diaphragmatic hernia (CDH) and necrotizing enterocolitis (NEC). Specifically, the Zani Lab has been studying the biology of extracellular vesicles (exosomes) derived from a variety of sources, including stem cells, asa regenerative medicine tool to address these conditions.  
  2. Outcomes research in paediatric surgery, aiming to provide the best available evidence on known controversies in the management of pediatric surgical conditions such as appendicitis, gastroesophageal reflux, CDH, and NEC, through systematic reviews, meta-analyses, and randomized control trials.
