Rosalind Herman Gelbart is Professor of Child Language and Deafness in the Department of Language and Communication Science, City St George's, University of London. Ros trained as a speech and language therapist and specialised in clinical work with deaf people. She has maintained her clinical work alongside research and training speech and language therapists. Her research interests are related to language acquisition, assessment, and interventions with deaf people.

Charlotte Enns is Professor Emerita in the Faculty of Education at the University of Manitoba. Her background is in speech-language pathology but, despite her clinical training, she has always considered herself more of an educator than a clinician, which has strongly influenced her work with the language rights of deaf children. Charlotte's research is focused on the bilingual education of deaf students, with a particular emphasis on language and literacy acquisition and assessment. She believes it is critical to involve deaf people in research about deaf people to gain the valuable scientific and humanitarian contributions provided through their embodied knowledge.
