Staff Profile

After attaining undergraduate and postgraduate masters degrees in psychology from the University of Edinburgh in 2013, and Loughborough University in 2014, I worked as a researcher in cognitive ageing at Nottingham Trent University before moving to Newcastle in 2017.

I completed my PhD in Neuroscience/Translational and Clinical Research in 2020, exploring the longitudinal progressions of mild cognitive impairment with Lewy bodies and Alzheimer's disease, before joining Newcastle University as a postdoctoral Research Associate in 2021.

My research concerns changes in cognitive impairment, clinical function, and biomarkers over the course of normal ageing and developing neurodegenerative diseases, with a particular focus on early-stage Lewy body disease. I am particularly interested in characterising variation within clinical syndromes; for example, in identifying declining and non-declining phenotypes, and considering how life events, local deprivation, and frailty may contribute to better or worse cognitive health in ageing.

My current research contributions involve the LewyPro and SUPErB cohort studies at Newcastle University, and the national Brains for Dementia Research programme.

I have contributed to the School of Psychology Research Methods modules for a number of years, and supervise undergraduate and postgraduate projects in the Biomedical Sciences and Neuroscience.
