Sarah Theodoroff, Ph.D.

Telephone: 503-220-8262, x51948

Current appointments:

  • Research Investigator, NCRAR
  • Associate Professor, Department of Otolaryngology/HNS, Oregon Health & Science University
  • Adjunct Professor, Department of Speech & Hearing Sciences, Portland State University
  • Adjunct Professor, School of Audiology, Pacific University

Research interests:

My avenue of research focuses on the poorly understood perceptual consequences of noise, specifically tinnitus, hyperacusis, and noise sensitivity. My work is informed by my clinical background and aims to improve patient-centered clinical protocols and increase awareness of the needs of patients with these elusive auditory conditions among medical professionals and the public.
