UNRAVELING THE MYSTERY BEHIND STUTTERING
July 27, 2022
UD researchers study the brains of children with persistent stuttering to determine what hinders recovery.
RESEARCHERS LOOK FOR BIOLOGICAL REASONS BEHIND STUTTERING
UNRAVELING THE BIOLOGY OF A MYSTERIOUS CONDITION: STUTTERING
Researchers are delving into the biological underpinnings of stuttering.
EXAMINING THE SCIENCE OF STUTTERING, FROM CHILDHOOD INTO ADULTHOOD
Like presidential candidate Joe Biden, researcher Evan Usler has used his personal experience to help those with speech disorders.
