Dr. Nwawka completed her fellowship in musculoskeletal imaging at HSS after which she joined the Radiology and Imaging Department as an assistant attending radiologist. As a fellow, Dr. Nwawka participated in numerous research projects which have gone on to produce multiple publications in the radiology and orthopedic surgery literature. She continues to present her research at national and international meetings and has been invited to lecture on topics including nerve imaging musculoskeletal ultrasound and quantitative imaging techniques. Trained in all realms of musculoskeletal interventions and imaging including MRI, CT and ultrasound, Dr. Nwawka is particularly interested in nerve imaging and musculoskeletal ultrasound. She is the principal investigator of several grants awarded by the American Institute of Ultrasound in Medicine (AIUM), General Electric Healthcare (GEHC), the National Basketball Association (NBA) and the Radiological Society of North America (RSNA).
