Research Interests
Dr. Nader S. Dahdaleh is a board certified neurosurgeon who treats all surgical diseases of the brain and spine. However, he has a specific interest in both minimally invasive spinal techniques for adult degenerative spinal disease, spinal tumors, trauma, spinal column deformity, and disorders affecting the craniovertebral junction. Dr. Dahdaleh obtained his undergraduate degree in biology graduating with distinction from the American University of Beirut. He also obtained his medical degree from the American University of Beirut graduating with merit and ranking first in his class. He then completed his training in Neurological surgery at the University of Iowa hospitals and clinics. Subsequently, he completed an adult deformity fellowship at the department of orthopedics at the University of Iowa hospitals and Clinics and a minimally invasive spine fellowship at Northwestern University, Feinberg School of Medicine. He has over 120 peer-reviewed papers and book chapters and has published in high profile journals including: Nature Neuroscience, Cell, Proceedings of the National Academy of Sciences, American Journal of Human Genetics, Journal of Neurosurgery and Spine. He has special interest in minimally invasive spine surgery, spinal trauma, disorders affecting the craniovertebral junction, spine biomechanics, and gait analysis.
