- Profile
-
I am a Professor and the Head of the School of Computer Science at the University of Sheffield. My research is situated at the intersection of speech technology, AI, and healthcare, where I focus on developing machine learning systems that use spontaneous speech and language biomarkers to detect early signs of clinical conditions.
A major focus of my work is CognoSpeak™, an automated, remote assessment tool for cognitive impairment. We are currently expanding these technologies to support stroke recovery and Motor Neurone Disease (MND).
Beyond my research, I am a dedicated advocate for Equality, Diversity, and Inclusion (EDI), having previously served as the Faculty Director of EDI and led the University to a successful Athena SWAN Silver institutional renewal. I currently have over 3,800 citations and an h-index of 36, reflecting my commitment to bridging AI innovation with impactful, real-world healthcare solutions.
- Research interests
-
Her research interests are in the use of speech and language processing in the healthcare domain. She has considerable experience in the areas of recognition of disordered speech, automatic processing of conversations and the automatic detection and tracking of paralinguistic information such as emotions and general interactional behaviours. Her research has been supported by EU, UKRI, NIHR, Google and various charities like Rosetrees Trust and the Psychiatry Research Trust. She has considerable experience in leading highly interdisciplinary research projects including being the technical lead in the development of the CognoSpeak system for using AI to detect early signs of dementia.
