Research Profile

My research interests include surgical correction of scoliosis using Vertebral Body Tethering, as well as operative and non-operative treatment of achondroplasia and other skeletal dysplasias. In support of my research, I have received grants from various pharmaceutical and medical equipment companies, including Striker Spine, BioMarin Pharmaceuticals and the Pediatric Orthopaedic Society of North America. I have had the honor of presenting my work both nationally and internationally and have publications in the Journal of Neurosurgery: Pediatrics, The Spine Journal, Journal of Pediatric Orthopaedics and the American Journal of Orthopedics. Innovation and technology are critical in offering state-of-the-art care, and I am thankful to be able to use my research to improve the lives of my patients and their families.
