Dr. Mellissa Bortz is an assistant professor in the Department of Communication Sciences and Disorders and a nationally certified speech-language pathologist. Her research and clinical interests focus on language acquisition and language disorders across the lifespan. Originally from South Africa, Dr. Bortz is especially interested in understanding how speech-language pathologists can best serve individuals in culturally and linguistically diverse areas of the globe. Towards this goal, she has developed a database of speech and language materials devised for use throughout Africa. She is currently developing a Global Language Assessment Template and also collecting code-switching data in people with aphasia in South Eastern Zone Bantu languages.
Dr. Bortz is a member of the American Speech-Language-Hearing Association (ASHA). She has completed ASHA’s Leadership Development Program and previously served on the ASHA International Issues Board. She is also a member of the South African Speech-Language-Hearing Association African Connections Sub-committee.
At St John’s, Dr. Bortz has been awarded the Faculty Mission Certificate by the Vincentian Centre for Church and Society and is the faculty moderator for the St. John’s NSSLHA chapter on the Queens campus. She enjoys mentoring and encourages interested students to participate in her research.
