My clinical interests and expertise are complement mediated renal disease,high risk transplant,parathyroid disorders, and kidney stones.

My contribution to genetic research has revealed molecular defect of different phosphate-wasting disorders. These efforts led to the identification of a novel GLUT2  mutations in a consanguineous family with extremely severe, longstanding hypophosphatemetic rickets, but surprisingly without major changes in the regulation of blood sugar. I also participated in molecular genetic studies identifying novel NPT2c mutations leading to nephrocalcinosis, and novel potassium channel mutations causing Bartter syndrome.
