Ann Ragin

Ann Ragin, PhD, is a Research Professor in the Department of Radiology at the Feinberg School of Medicine, Northwestern University. Her work focuses on quantitative MRI and brain network analysis to investigate aging effects and viral infections including HIV and COVID-19. She maintains active affiliations with the Institute for Public Health and Medicine (IPHAM), Northwestern University Clinical and Translational Sciences Institute (NUCATS), Northwestern University Institute of Neuroscience (NUIN), Robert J. Havey, MD Institute for Global Health, and Simpson Querrey Institute for Epigenetics.

Her academic credentials include a PhD from Northwestern University (1987) and postgraduate training at the University of Chicago (1989), where she completed a postdoctoral fellowship in Quantitative Methods.

Dr. Ragin's research program integrates advanced imaging techniques with clinical neuroscience:

• Development of quantitative MRI methodologies for in vivo brain measurement
• Brain network analysis for early neural injury detection
• 4D flow imaging applications in cerebral blood flow assessment
• Investigation of neuroinflammation in HIV/AIDS and aging populations
• Structural-functional neuroimaging correlations in viral infections

Her recent publications reveal a dual research trajectory: computational neuroscience innovations (tensor-based graph networks for brain analysis) and clinical applications in cardiopulmonary imaging (pulmonary hypertension biomarkers). This work bridges machine learning, neurology, and cardiology through collaborative NIH-funded studies with the AIDS Clinical Trials Group.

Professional leadership includes continuous membership in the AIDS Clinical Trials Group (2013-present), Conference on Retroviruses and Opportunistic Infections, and International Society for Magnetic Resonance in Medicine (2002-present), with prior service on the Chicago Society for Neuroscience Council (2003-2005).

While specific grant details remain undisclosed per institutional policy, her ACTG membership and multi-institute affiliations indicate substantial involvement in federally funded research. No advisee information appears in public profiles, though her 99 publications suggest extensive mentorship within collaborative projects.

Current initiatives focus on multimodal brain network analysis for HIV-related neurocognitive disorders and quantitative MRI biomarkers for pulmonary hypertension, leveraging Northwestern's advanced imaging infrastructure across multiple research consortia.
