Short Bio:

Dr. Popescu graduated from the University of Medicine and Pharmacy in Craiova, Romania. After completing a residency in forensic pathology in Romania, she completed on AP/CP residency at Upstate Medical University in Syracuse, NY. This was followed by a fellowship in pediatric pathology at Cincinnati Children’s Hospital Medical Center. She joined the Children’s and Women’s Health Centre of British Columbia as a staff pathologist and UBC Faculty of Medicine as a Clinical Assistant Professor in July 2007. Her main interest is in GI pathology and pediatric solid tumors.

Research Interest

  • Gatrointestinal pathology
  • Pediatric tumors


My current practice is based on the diagnosis and study of neoplastic and non-neoplastic diseases in children. My main interest is in pediatric solid tumors, gastrointestinal and liver pathology, and sudden infant death pathology.

Current Projects

The project I am working now is about liver and renal histopathology in sudden infant death cases in aboriginal children homozygous for CPT1AP479L mutation. This mutation is associated with recurrent attacks of hypoketotic hypoglycemia during fasting, fever, and intercurrent illnesses. Clinical presentation of CPT1A deficiency is variable and ranges from sudden death in infancy to liver disease with hepatomegaly later in life. It appears to have specific histological findings in sudden death cases of homozygous infants homozygous for CPT1AP479L mutation compared with heterozygous and wild type cases.
