My Biography & Research


As a pediatric neuroradiologist, I specialize in brain, spine, and head and neck imaging, with my primary interests being head and neck imaging and medical education.

During my 20-year career in the military, I had the opportunity to pursue an academic track in medical education, which included assignments as a radiology residency program director and department chairman. Having completed neuroradiology subspecialty fellowships at the University of Cincinnati and Cincinnati Children’s, I had always hoped for the chance to return to Cincinnati Children’s as a member of the teaching faculty following my military service.

As luck would have it, I was fortunate enough to return to Cincinnati Children’s in 2017 as director of the Pediatric Neuroradiology Fellowship Program and was subsequently appointed as director of the Division of Neuroradiology in 2019.

I look forward to continued emphasis and opportunities in the realms of medical education and clinical leadership.
