I’m a postdoctoral research associate working in the Division of Psychology, Communication and Human Neuroscience at The University of Manchester. I research hearing loss in people with dementia living in care homes and in the community. Currently, I am investigating how common hearing loss is in people with dementia and how accessible hearing assessments and audiology services are for people with dementia. Prior to this, I completed my PhD on hearing loss within care homes and how to improve hearing care provided to residents with dementia. I worked with Rebecca Millman, Piers Dawes, Christopher Armitage and Iracema Leroi on this project.
I have a degree in Psychology and previously worked in care homes as a care assistant.
