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.
