His research focuses on primary vesicoureteral reflux in children and a separate study on focal segmental glomerulosclerosis, a disease that attacks the kidneys' filtering system.

Vesicoureteral reflux is a common congenital abnormality that is associated with recurrent urinary tract infections in children. With normal urination, the bladder contracts and deposits the urine through the urethra. In children with VUR, there is an abnormal flow of urine that goes back up into the ureters and sometimes to the kidneys. This reflux exposes the kidneys to infection, which can cause serious damage. The injury to the kidneys may result in renal scarring, which may cause high blood pressure later in life, or even kidney failure.
