Profile

Professor Christensen obtained her M.Sc. and a Ph.D. degrees from Aalborg University, Denmark, in 1996 and 2002, respectively. In 1998, she was a visiting researcher at IDIAP, Switzerland. From 2000, she worked as a research associate on numerous national and international projects in the Speech and Hearing group in Sheffield before taking up her lectureship in 2015. She was subsequently appointed a senior lecturer (2019) and chair (2022) in the department. 

She is the current Head of School and has a long-term interest in EDI (Equality, Diversity and Inclusion), serving as the Faculty Director of EDI (2020-2022).

Her main research interests are 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.

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.
