Research Topics

Dr. Hammoud's research interests target 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. Research in her laboratory focuses on further understanding the pathophysiology of cognitive dysfunction in the setting of HIV infection. Current projects include neurotransmitter PET imaging in SIV-infected monkeys, imaging neuro-inflammation in humans and in animal models of HIV, as well as studying the relationship between HIV-associated neurocognitive dysfunction and vasculopathy, both in animal models and in patients, using a variety of advanced techniques such as magnetic resonance imaging, magnetic resonance spectroscopy and positron emission tomography. Hammoud is a member of the Society of Nuclear Medicine and serves as a member of the Center for Molecular Imaging Innovation and Translation (CMIIT) Program Task Force.


Dr. Hammoud attended college at the American University of Beirut in Lebanon, where she earned a bachelor's degree in biology in 1992 and an M.D. degree in 1996. 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 for three years before joining the neuroradiology faculty at NIH. Hammoud is board-certified in diagnostic imaging by the American Board of Radiology, and has completed fellowships in neuroradiology and PET imaging. She is currently a tenure track investigator in the Center for Infectious Disease Imaging (CIDI), a joint initiative between Radiology and Imaging Sciences at the NIH Clinical Center and the National Institute of Allergy and Infectious Diseases (NIAID).
