Dr. Dima A. Hammoud is a tenured Senior Investigator in Radiology and Imaging Sciences at the NIH Clinical Center and deputy director in the Center for Infectious Disease Imaging, a joint initiative between Radiology and Imaging Sciences at the NIH Clinical Center and the National Institute of Allergy and Infectious Diseases. She is also a neuroradiologist at Radiology and Imaging Sciences at the NIH Clinical Center.
Dr. Hammoud attended college at the American University of Beirut in Lebanon, where she earned a bachelor's degree in biology and an MD degree. After completing a residency in diagnostic radiology at the American University of Beirut-Medical Center, she joined the division of neuroradiology at the Johns Hopkins Hospital as a fellow. After completion of her fellowships, she joined the neuroradiology faculty at Johns Hopkins as assistant professor before eventually joining the neuroradiology faculty at the NIH Clinical Center.
Dr. Hammoud is board-certified in diagnostic imaging by the American Board of Radiology, and has completed fellowships in neuroradiology and PET imaging. She currently serves as chair of the "Imaging of Infections interest group" at the World Molecular Imaging Society, Chair of the animal care and use committee at the NIH Clinical Center, committee member of the intramural PET Steering Committee at NIH and member of the scientific program committee of the WMIC since 2021.
Dr. Hammoud’s research interests include the development of preclinical, translational and clinical molecular imaging applications to improve the understanding of the pathophysiology of infection, and to provide reliable imaging biomarkers of infectious diseases. Current research in the laboratory focuses on the development and validation of novel fungal-specific imaging biomarkers in animal models of infection which can then be translated to human applications, using non-invasive molecular imaging techniques, mainly positron emission tomography.
Another interest of the lab is utilizing molecular imaging to better understand the pathophysiology of HIV in the brain and periphery and to identify HIV reservoirs.
Dr Hammoud also collaborates with the NIAID Integrated Research Facility, a biosafety level (BSL)-2 to BSL-4 biomedical research facility based in Fort Detrick, MD, to image high-consequence viral infections such as Ebola, Nipah and Lassa viruses.
