Brain and Movement (BAM) Research Group

I am the Janet Owens Parkinson's UK Senior Research Fellow. I am currently part of the Brain and Movement (BAM) Research Group led by Professor Lynn Rochester at the Translation and Clinical Research Institute at Newcastle University, and based at the Clinical Ageing Research Unit (CARU).

My translational research programme aims to determine the optimal measurements and mechanisms underpinning neuropsychiatric symptoms and delirium in the context of Parkinson’s, and how these conditions are associated with cognitive and motor decline. Ultimately, my goal is to improve the recognition and management of these distressing symptoms and conditions, and to improve the quality of life and long-term health outcomes of people affected by Parkinson’s.
