Research Description
Seth Smith, Ph.D., earned a B.S. in Physics and a B.S. in Mathematics from Virginia Tech and a Ph.D. in Biophysics ad Biophysical Chemistry from Johns Hopkins University. After earning his PhD, he joined the research faculty at Kennedy Krieger Institute at the F.M. Kirby Research Center where her remained until 2009. In 2009, he joined the Vanderbilt faculty as Assistant Professor of Radiology, Biomedical Engineering and Physics. In 2015 he was appointed Associate Professor in Radiology and Radiological Sciences, Biomedical Engineering, and Ophthalmology. He was named to the 2017 class of Chancellor Faculty Fellows.Since 2010, he has served as Director of the Center for Human Imaging at Vanderbilt University Institute of Imaging Science. His research is focused on translation of advanced, quantitative MRI methods into human diseases such as Multiple Sclerosis and Optic Neuropathies focusing on quantitative assessment of the spinal cord and optic nerves at both high and low field strengths.
