Dennis Drayna, Ph.D.
Chief, Laboratory of Communication Disorders
Chief, 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 and since then has focused on applying the tools of human genetics and genomics to a range of topics that span 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 current work has a major focus on the genetics and neuroscience of stuttering.
