Postdoctoral Researcher

  • Psychometric Analyst - European Prevention of Alzheimer's Dementia (EPAD)
  • Data Coordinator - Dementias Platform UK (DPUK)

Psychometric and statistical analysis of large cohort data for dementia and age-related research

Sarah is a cognitive neuropsychologist with interests in healthy cognitive ageing and cognitive decline associated with neuropathological disorders such as mild cognitive impairment (MCI) and dementia. Using cognitive, psychometric and physical fitness testing her PhD research investigated how lifestyle activities, mental health and aerobic fitness moderated cognitive function in old age, specifically, RT variability. She also conducted a functional magnetic resonance imaging (fMRI) study exploring the neural correlates of response time variability in older adults. Prior to her current position, she completed a 2-year post-doctoral fellowship at the University of Leeds where she was project lead on an NHS-funded project investigating physical and cognitive predictors of falls and frailty in older adults and was also involved in research exploring the effects of depression, anxiety and stress on cognition across the lifespan.

Her expertise includes using structural equation modelling (SEM) which facilitate the ability to explore multiple moderating and mediating variables in a single analysis. She is now a member of the team working for Professor John Gallacher on the European Prevention of Alzheimer's Dementia (EPAD) study. In this role, she is conducting psychometric analyses on UK Biobank mental health data using item response theory (IRT) and SEM. She is also designing computer adaptive tests (CATs) which could refine scale delivery and subsequent analyses in future research epidemiological studies such as EPAD. Sarah is also data co-ordinator for Dementias Platform UK (DPUK) where she co-ordinates access to cohort data for researchers and is working with Professor Gallacher to design a data ontology solution for DPUK.
