Clinical Description
Dr. McKnight is an Assistant Professor of Radiology and Radiological Sciences within the division of Neuroradiology at Vanderbilt University Medical Center and Medical Director of Inpatient Radiology for Vanderbilt University Hospital. He joined the VUMC faculty in 2016.
Dr. McKnight attended Duke University where he received a B.S. in biology with distinction in 2004. He also obtained minors in economics and chemistry. He received an intramural research training award where he conducted neurogenetics research for one year at the National Institutes of Health. He subsequently returned to Oregon and attended Oregon Health and Sciences University where he obtained his M.D., graduated cum laude and received Alpha Omega Alpha membership.
Dr. McKnight received his diagnostic radiology and neuroradiology fellowship at the University of Michigan, where he received awards for Outstanding House Officer Research Excellence in 2014, the Radiological Society of North America Fellowship grant in 2015 and the Roentgen Research Award in 2016.
Since joining the faculty at Vanderbilt University Medical Center, Dr. McKnight has focused his research efforts on advanced imaging of the glympatic system (Glial LYMPHATIC system) which is a collection of emerging concepts pertaining to how cerebrospinal fluid functions to clear central nervous system waste products. He is a Co-Investigator on numerous related grants funded through the National Institutes of Health, the Department of Defense and the National Multiple Sclerosis Society. Dr. McKnight was awarded the VUMC Catalyst Research award in 2020. He received the 2021 Radiological Society of North America Research Scholar Award and is the primary investigator on a grant entitled: Magnetization Transfer Imaging of the Human Spinal Cord and Cerebrospinal fluid to Characterize Myelin Metabolism in Mulitple Sclerosis.
Dr. McKnight serves on the Vanderbilt Radiology Resident Selection Committee and the Department or Radiology Amplifying innovation Committee. He is a member of the International Hydrocephalus Imaging Working Group, the Radiological Society of North America, the America Society of Neuroradiologists and the Association of University Radiologists.
