Personal profile

Research Interests

Quantitative Magnetic Resonance Imaging strategies for in vivo measurement of the brain to investigate effects of aging and of viruses, particularly HIV infection. Brain network analysis to investigate effects of aging and for early detection of neural injury. Collaborative projects involve applications of 4D flow imaging to investigate alterations in cerebral blood flow and relation to brain status.
