معرفی
Nasim Sheikh-Bahaei is an Assistant Professor of Clinical Radiology and Neurology at the Keck School of Medicine of the University of Southern California, where she serves as Medical Director of Radiology at Keck Hospital and Section Chief of Neuroradiology. Her work focuses on neuroimaging biomarkers for neurodegenerative diseases and dementias, particularly using advanced MRI and PET techniques to study amyloid, tau, and microvascular changes.
- Education:
- M.D. from Tehran University of Medical Sciences
- Ph.D. in Alzheimer’s disease imaging from University of Cambridge
Research Interests:
She integrates multimodal neuroimaging to investigate:
- Synaptic function in Alzheimer’s and its link to amyloid/tau
- MRS-measured neurotransmitter interactions with PET/tractography
- Microvascular alterations (cerebral microbleeds, perivascular spaces) in AD, migraine, and normal pressure hydrocephalus
- Development of automated software for perivascular space quantification
- Optimization of PET tracers and quantitative analysis systems
- 7T MRI studies on migraine microvascular/perfusion changes
Publication Trends:
Recent work emphasizes deep learning for MRI harmonization, perivascular space analysis as a vascular biomarker, synaptic/metabolic imaging, and CAA/pathology associations. Techniques span T1-weighted artifacts, 3D TSE-based flow suppression, and texture analysis for early dementia detection.
Leadership & Collaborations:
As a Co-Investigator in USC’s ADRC imaging core and member of Laboratory of Neuroimaging (LONI), she leads projects on glymphatic system dysfunction in CSF flow disorders. Her research is funded by the National Institute for Health Research (NIHR) and institutional grants.
