Greg E. Davis, M.D., M.P.H., was an associate professor of otolaryngology at the University of Washington and was the director of Rhinology and Endoscopic Skull Base Surgery. Dr. Davis earned his medical degree from the University of Washington School of Medicine, then completed a seven-year residency in otolaryngology - head and neck surgery at UW. During his residency, he completed a two-year clinical research fellowship where he earned his Master of Public Health, during which he focused on clinical trial design and management, biostatistics, and epidemiology. After residency, he traveled to Adelaide, Australia, and spent additional time training with P.J. Wormald, a world-renowned rhinologist.

Dr. Davis joined the faculty in the Department of Otolaryngology at the University of Washington in September 2007. He was awarded a highly competitive K12 (KL2) career development grant from the NIH and UW's national Clinical and Translational Science Award (CTSA) site. This five-year award allowed him to pursue clinical research while also building his rhinology practice at  UW Medical Center.

Dr. Davis continues to perform research in many areas related to rhinology. He is studying chronic rhinosinusitis, olfactory loss, cystic-fibrosis-related sinusitis, national trends in chronic sinusitis surgery, and even a project dealing with autism.

Dr. Davis has served as an expert witness on both a national and local level. He played a key role in representing the plaintiffs in Zicam-related litigation where an over-the-counter nasal spray had been implicated in causing smell loss, supported with research his team had performed showing that the nose spray destroyed human and mouse olfactory tissue. He has also served as an expert witness in several rhinology-related medical legal cases.

Dr. Davis is a physician-educator. He has put on numerous national sinus surgery courses where he provided advanced training in sinus surgery techniques, including co-directing the Seattle Otology and Advanced Rhinology course and UW Resident Sinus Surgery courses. He was also the course director for the international sinus surgery course, Japan Lab.

Dr. Davis has an active family life. He is married and has two children. He has coached baseball for many years and is the president of a select baseball program comprised of teams ages 9-12. He enjoys most outdoor activities with his family including mountain biking, skiing, rock climbing, and back country camping.
