Education

  • University of Western Ontario, London, Ontario, Canada, 1992
  • University of Toronto, Institute of Medical Science, Hospital for Sick Children, Toronto, 1998

Research Interests

  • To understand the mechanisms governing the migration of intestinal epithelial cells during conditions of intestinal inflammation, such as necrotizing enterocolitis, Crohn's disease and infection. This information will hopefully provide novel therapeutic targets for treating these disorders.
  • To understand the mechanisms of phagocytosis of pathogens by macrophages in neonates during conditions of inflammation. This information will hopefully provide insights for enhancing the immune system during critical illness.
  • Initiating a large review of all patients with congenital diaphragmatic hernia to determine the optimal timing and mode of surgical repair.
  • Initiating a retrospective and prospective review of patients with tracheo-esophageal fistula to determine the factors influencing outcome in these patients.
  • Retrospective review of patients who have sustained traumatic intestinal injuries, to determine the optimal diagnostic modality and to determine strategies to improve their outcome

Certifications

  • The American Board of Surgery, Pediatric Surgery
  • The American Board of Surgery, General Surgery
  • Royal College of Physicians and Surgeons of Canada
