Jochen Schacht, Ph.D.

Professor Emeritus, Otolaryngology-Head and Neck Surgery


Dr. Jochen Schacht received his B.S. in chemistry from the Friedrich-Wilhelms-Universitat in Bonn, Germany (1962). He then completed his M.S. in chemistry (1965) and Ph.D. in biochemistry (1968) from the Ruprecht-Karls-Universitat in Heidelberg, Germany. His postdoctoral fellowships included the Department of Biochemistry at the University of Heidelberg, Germany (1969) and the Mental Health Research Institute here at the University of Michigan (1972).

Areas of Interest

Dr. Schacht's research interests are three-fold. They include:

  • How the ear works: biochemical and cell biological studies of cell communication and regulatory mechanisms in the inner ear (second messengers, transcription factors, gene expression)
  • How drugs cause deafness: mechanisms and prevention of drug-induced hearing loss (with emphasis on aminoglycoside antibiotics: gentamicin, kanamycin, streptomycin)
  • International collaboration on chemotherapy for the 21st century: development of next-generation aminoglycosides with high efficacy and low ototoxic potential
