Fellowship in Sleep Medicine at North Shore University Hospital & Long Island Jewish Medical Center (NS/LIJ)

The Division of Pulmonary, Critical Care and Sleep Medicine in the Department of Medicine offers a one-year fellowship training program in sleep medicine. This ACGME-accredited program provides sleep medicine fellows with broad clinical and research experience. The program is based at the Northwell Health Sleep Disorders Center, which is one of the largest sleep medicine centers in the region, and is fully accredited by the American Academy of Sleep Medicine.

Fellows are taught by a multidisciplinary sleep medicine faculty with backgrounds in pulmonary medicine, otolaryngology, dental sleep medicine, psychiatry and behavioral sleep medicine. Trainees benefit from a comprehensive experience in the diagnosis and management of adult and pediatric patients with a broad range of sleep disorders, both in the inpatient and outpatient settings. Fellows are encouraged to participate in scholarly activities that involve teaching, basic and clinical research in sleep medicine.

They also benefit from the resources of the Center for Heart and Lung Research of the Feinstein Institutes for Medical Research. A weekly sleep medicine conference includes clinical, core and multidisciplinary topics. The program is available to board-eligible internists, neurologists and psychiatrists.


Our clinicians, educators and researchers are dedicated to delivering the highest quality care, while continually pushing the boundaries of knowledge.
