Projects

My research focuses on iron metabolism and its disturbances in human disease. My major aim is to understand the regulatory circuitry underlying systemic iron homeostasis. We concentrate on the iron hormone hepcidin and its regulatory “target receptor” ferroportin. Since both the excess of hepcidin (leading to anemia) and its deficiency (causing iron overload) must be prevented, a central goal of our work is to decipher the control of hepcidin expression employing network/systems-based analyses by integrating transcriptomic and proteomic analyses, mouse models and genome-wide siRNA screens.
