Biography of Professor Jae Jun Song, MD

Dr. Jae Jun Song is an internationally recognized otolaryngologist, neuroscientist, and medical innovator whose career has been devoted to advancing the understanding and treatment of ear diseases and brain disorders. He serves as a full Professor of Otorhinolaryngology–Head and Neck Surgery at Korea University Guro Hospital in Seoul, where he has practiced and conducted research for more than two decades, establishing himself as a leading authority in otology and auditory neuroscience.

Dr. Song's clinical and academic expertise centers on disorders of the ear, with a particular emphasis on tinnitus, chronic otitis media, sudden sensorineural hearing loss, and related auditory pathologies. Recognizing that many ear disorders are inseparably linked to dysfunction in central brain networks, he has pioneered a translational research agenda that bridges peripheral auditory pathology with cognitive and neuropsychiatric conditions. His triple-network model of tinnitus, developed in collaboration with international colleagues, has become an influential framework for understanding how aberrant functional connectivity in the fronto-parietal, salience, and default-mode networks underlies the persistent perception of phantom sounds.

To date, Dr. Song has authored more than 150 peer-reviewed international publications, accumulating over 4,500 citations. His recent work, published in high-impact journals such as Brain Stimulation, Neuromodulation, and the International Journal of Neuropsychopharmacology, examines how transcutaneous auricular vagus nerve stimulation (taVNS) modulates cortical excitability, inflammatory biomarkers, and neuroplasticity. Through collaborations with Harvard Medical School, Spaulding Rehabilitation Hospital, Seoul National University, and Hallym University, he has produced systematic reviews and mechanistic analyses supporting taVNS as a therapeutic tool for major depressive disorder, chronic tinnitus, cognitive decline, and inflammation-driven conditions including gouty arthritis.

Dr. Song's career exemplifies a rare integration of rigorous clinical otology, cutting-edge neuroscience, and entrepreneurial commercialization. By conceptualizing the ear as a therapeutic gateway to the brain, he has reshaped contemporary approaches to neurotologic disease and positioned Korea at the forefront of non-invasive bioelectronic medicine for ear and brain disorders.
