Sam S. Webb
DPhil
Postdoctoral Research Fellow
Overview
I am a postdoctoral researcher funded by a Stroke Association Postdoctoral Fellowship awarded in August 2024, and was previously a research assistant and MSc/DPhil student in the Translational Neuropsychology Group. My general interests are in how we measure cognition following stroke. This involves investigating whether a test does actually measure what we intend it to measure, and whether it gives us a reliable index of someones cognitive status at a particular time point and beyond.
Core research interest
- Validation of cognitive impairment screening tools to provide a greater evidence-base for clinical decision making.
Research Contributions
I have heavily contributed to data curation, analysis, manuscript writing, and dissemination for the Oxford Cognitive Screen (OCS), the OCS-plus, Tele-OCS, OxMET, Mini-OCS, and other cognitive assessments. Sam is now validating the new Multistage Cognitive Screen – Stroke (MCS-Stroke) which aims to be suitable for any time post-stroke and any stroke setting.
