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.

My background is in psychology and my research focus has been in patients with Parkinson’s disease and Lewy body dementias over the last ten years. I have a particular interest in the neuropsychology of Parkinson's disease and delirium. I have an interest in mathematics and statistics, and have an interest in advanced statistics to analyse complex, longitudinal data. I am passionate in research that will ultimately improve the care and quality of life of people with Parkinson’s disease.
