Tribute to the Quintessential Researcher, Clinician, and Mentor: Audrey Holland

The purpose of this special issue of Aphasiology is to honour Dr. Audrey Holland and her prolific research and clinical achievements over the past 50 years. The issue has been constructed to exemplify the breadth of Dr. Holland's influence not only in terms of research topics (e.g., aphasia, dementia, research methodology) but also geographic span, with contributing authors from around the globe. All contributors, some former mentees and others contemporaries and collaborators, have been similarly inspired through their interactions with Dr. Holland to advance the field of neurogenic communication disorders, as is reflected in each of their papers.
