"Quantitative MRI Across the Lifespan"
Keating 103 | Zoom link
Hosted by the BIO5 Brain and Body Imaging Center and Biomedical Engineering in honor of the late Arthur F. Gmitro.
Andrew Alexander is a professor of medical physics and psychiatry at the University of Wisconsin-Madison and director of the Waisman Quantitative Brain Imaging Technology Laboratory. He received his doctorate in optical sciences from the University of Arizona in 1994, training with Arthur Gmitro. He developed a research program focused on diffusion brain imaging at the University of Utah and joined the faculty at the University of Wisconsin in 2001.
His research focuses on the development and application of advanced quantitative MRI methods for neuroimaging across the lifespan, with particular emphasis on diffusion MRI and relaxometry. He has applied these methods to investigate pediatric brain development, cerebral palsy, traumatic brain injury, autism, Down syndrome, anxiety, depression, adult aging and Alzheimer's disease risk.
His research program has been continuously funded by the National Institutes of Health since 1998. Alexander is a fellow of the International Society for Magnetic Resonance in Medicine and a fellow of the American Institute of Medical and Biological Engineering.
"Since my experience as a graduate student working with Art Gmitro, we developed a radial diffusion MRI technique that ultimately led to my research program focused on quantitative MRI methods using diffusion-weighted imaging and relaxometry using radial k-space sampling," Alexander said. "This presentation will focus on the development of technologies for quantitative diffusion MRI and 3D relaxometry with applications to early brain development and aging."
