PhD, University of Naples Federico II, Naples, Italy
Dr. De Giorgi earned her master's degree in molecular biology and her PhD in biochemistry from the University of Naples Federico II. She is currently the Chief of the Infectious Diseases Section at the NIH Department of Transfusion Medicine.
Dr. De Giorgi has over a decade of experience in both academic and clinical settings, including a postdoctoral fellowship at the National Institutes of Health (NIH), where she investigated the correlation of hepatitis viruses and cancer and developed a multiplex platform able to screen more than 30 blood borne pathogens in one test. She has published over 50 peer-reviewed articles and has been presenting her work at international conferences, sharing her insights on viral genomics and diagnostics.
As the director of the Transfusion Transmitted Viruses lab (TTV) Laboratory and the Molecular Virology Lab (MVL) at the Department of Transfusion Medicine, Dr. De Giorgi leads a multidisciplinary team dedicated to advancing molecular techniques for identifying and characterizing emerging and re-emerging infections in the blood supply, and address possible mechanisms whereby hepatitis viruses may contribute to lymphomagenesis and other hematologic malignancies. Her research not only contributes to basic science but also has practical applications in outbreak management and testing platform development.
Dr. De Giorgi is also the DTM Associate Director for Research and a faculty for the DTM ACGME-accredited Transfusion Medicine Fellowship Program. She serves as member of the transfusion-transmitted infectious diseases (TTID) committee for the International Society of Blood Transfusion (ISBT), the NIH CC Hospital Infections Committee and as reviewer and associate editor for multiple high-impact scientific journals.
