Valerie Shafer, professor and executive officer of Speech-Language-Hearing Sciences at the CUNY Graduate Center, moderates a discussion featuring Nancy Eng, associate professor in the Department of Speech-Language & Audiology at Hunter College; Kyomi Gregory-Martin, associate professor in the Communication Sciences and Disorders program at Pace University; and Michelle MacRoy Higgins, associate professor of Speech-Language Pathology at Hunter College.
