I have worked at Sheffield Hallam University since 2006 and led the introduction of Neuropsychology and Clinical Psychology teaching into the undergraduate curriculum. In 2008 I developed the MSc Clinical Cognitive Neuroscience course, one of the first to offer clinical placements to neuroscience students. My research focuses on technological innovation for NHS users and new diagnostic techniques, biomarkers and interventions in concussion, stroke, traumatic brain injury and movement disorder conditions. I am currently leading a team investigating the microbiome in relation to neuropathological conditions.
I began working at Sheffield Hallam University in 2006 and immediately set about creating neuroscience teaching and research provision. I created the Brain, Behaviour and Cognition Research group that has since expanded into the Cognition and Neuroscience Research Group. I was promoted to Reader in Neuroscience in 2015. I am a member of the departmental Research Lead Team, and also lead the Neurocognitive theme within the Centre for Behavioural Science and Applied Psychology. I am a Special Edition editor of Frontiers in Behavioural Neuroscience and OBM Neurobiology. My methodological expertise centres on retinal imaging, eye-tracking, cognitive and neuropsychological assessment, immersive technological developments for health care evaluation, and pioneering new approaches investigating the gut microbiome in neuropathology and health. I am the Postgraduate Research Tutor for our large departmental PhD community.
Social Sciences and Arts
I teach Neuropsychology and Cognitive Neuroscience at MSc level, supervise several MSc projects and PhD students.
Recent research projects include:
Developing an innovative computerised cognitive evaluation task to quickly assess cognitive sparing and deficit - funded by MRC and Grow Med Tech in collaboration with The University of Sheffield, Sheffield Teaching Hospitals, Rotherham and Doncaster NHS Trust, and HIVE IT
A feasibility study investigating microbiome profile pre- and post- probiotic/placebo intervention and symptom profile, quality of life and wellbeing in Parkinson's disease patients - In collaboration with Sheffield Teaching Hospitals, Sheffield Medical School and Department of Biosciences and Chemistry - Funded by the Creating Knowledge Implementation Plan.
Retinal Imaging as a diagnostic marker of concussive events and metabolic status in collaboration with Professor Charmaine Childs, Faculty of Health and Wellbeing, and Sheffield Teaching Hospitals.
