Dennis Drayna, Ph.D.
Scientist Emeritus (Laboratory of Communication Disorders and
Section on Genetics of Communication Disorders)
Dr. Drayna received his bachelor’s degree from the University of Wisconsin in 1976, and his Ph.D. from Harvard University in 1981, followed by postdoctoral training at the Howard Hughes Medical Institute at the University of Utah. He joined the NIDCD in 1997, focusing on applying the tools of human genetics and genomics to a range of topics that spanned the mission of the institute, including disorders of auditory pitch perception, variation in human taste perception, and disorders of voice and speech. Dr. Drayna’s work had a major focus on the genetics and neuroscience of stuttering.
Dr. Drayna retired in June 2019.
