About the Sleep Medicine Fellowship Program

Ohio State has a storied history in Sleep Medicine. Our lab was the second accredited sleep center in the United States, and the first SLEEP meeting was held in Columbus, Ohio, in 1986. The program has grown to serve as a tertiary referral center for a multitude of patients with a wide spectrum of sleep issues. The Sleep Medicine Fellowship was founded in 2007 and has trained a diverse group of fellows with backgrounds in pulmonary, pulmonary critical care, neurology, psychiatry, internal medicine, family medicine, internal medicine/ pediatrics, pediatrics, and pediatric pulmonary medicine. Our fellows have gone on to have successful careers in both academic and community medicine positions.

The sleep fellows work directly with a diverse range of faculty with backgrounds in pulmonary critical care, neurology, psychiatry, and internal medicine. They also rotate with otolaryngology, dentistry, and psychology. The fellows’ pediatric sleep medicine experience at Nationwide Children's Hospital Sleep Center allows the fellows to spend two one-month rotations where the focus lies solely on pediatrics. NCH is one of the top pediatric hospitals in the country with a comprehensive pediatric sleep program comprised of pulmonary, neurology, psychiatry, and psychology specialty backgrounds.

OSUWMC has a 14-bed free standing sleep lab, beds in the Brain and Spine Hospital, and a busy home sleep testing program. The sleep center runs about 3500 in lab polysomnograms and 1500 home sleep tests a year.

The OSUWMC sleep center has specialized clinical programs including:

  • Hypoglossal nerve stimulator
  • Phrenic nerve stimulator
  • Chronic respiratory failure
  • Neuromuscular disease
  • Multiple sclerosis sleep clinic
