Sarah Theodoroff, Ph.D.

Telephone: 503-220-8262, x51948

Current appointments:

  • Research Investigator, NCRAR
  • Assistant 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:

  • Develop a safe, practical, and cost-effective intervention for chronic tinnitus
  • Develop an effective paradigm to diagnose and assess hyperacusis and distinguish it from other decreased sound tolerance disorders 
  • Develop procedures to improve diagnostic, assessment, and treatment of auditory disorders
  • Explore the impact of military and non-military noise exposures on developing tinnitus, hearing loss, and disorders of decreased sound tolerance
