Dr. Dima A. Hammoud is senior investigator in Radiology and Imaging Sciences (NIHCC) and deputy director in the Center for Infectious Disease Imaging, a joint initiative between Radiology and Imaging Sciences and the National Institute of Allergy and Infectious Diseases. She is also a neuroradiologist at Radiology and Imaging Sciences since 2006.
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.
In 2006, she joined the neuroradiology faculty at NIH.
Dr Hammoud is board-certified in diagnostic imaging by the American Board of Radiology, and has completed fellowships in neuroradiology and positron emission tomography (PET) imaging.
She is a member of the Society of Nuclear Medicine and Molecular Imaging and Radiological Society of North America. She currently serves as a member of the Molecular Imaging Abstract Review Subcommittee of the Scientific Program Committee and Education Exhibits Committee at RSNA and has previously served as a Board member of the Center for Molecular Imaging Innovation and Translation Program Task Force at SNMMI.
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 pathogen specific imaging biomarkers of infectious diseases.
Research in her laboratory focuses on further understanding the pathophysiology of cognitive dysfunction and immune activation in the setting of HIV infection using non-invasive molecular imaging techniques, mainly PET. Current projects include PET imaging of glucose metabolism and neurotransmitter systems in HIV infected patients.
She is also an expert in imaging high-consequence viral infections such as Ebola, Nipah and Lassa viruses, in collaboration with the Integrated Research Facility (NIAID), a BSL-4 biomedical research facility based in Fort Detrick, Maryland. Another major interest of the Hammoud lab is the development and validation of pathogen-specific fungal PET imaging ligands, in animal models and eventually in patients.
