My primary research interest lies in the field of pediatric acute kidney injury (AKI), which is defined as an abrupt and often reversible decline in renal function. AKI is a common occurrence in pediatric patients admitted to hospital and is caused by a variety of factors including dehydration, toxic medications, and low oxygen states. My current research work is focused on AKI in the pediatric intensive care unit (PICU) population and how AKI affects the long term renal function of these patients, years after their initial renal injury.
My secondary research interest is in the world of pediatric hemodialysis, one of the major forms of renal replacement therapy utilized in children with chronic kidney disease. I am particularly interested in evaluating various methods for quantifying the dose of chronic hemodialysis in children with end-stage kidney disease so that we can properly identify those patients which are being adequately dialyzed or not.
