Ethan Johnson is a Clinical Research Associate in Radiology at Northwestern University. His current research focuses include development and implementation of reliable methods for quantifying hemodyamics from cardiovascular MRI and study of how hemodynamics interact with disease progression in patients with valvular and/or congenital conditions. His Ph.D. work at Stanford University in the department of Electrical Engineering included pulse sequence development and image reconstruction in MRI.
