Honorary Consultant Neurologist
Senior Clinical Lecturer in Neurology
My research interests are into non-invasive diagnostic tests for early dementia or cognitive impairment using electroencephalography (EEG) and conversation analysis.
I am a co-applicant on a NIHR Research for Patient Benefit (RfPB) Programme: PB-PG-0211-24079 – Using Conversation Analysis in the Differential Diagnosis of Memory Problems: a pilot study is using the technique of conversational analysis to explore how people with and without an organic memory disorder describe their subjective memory complaint. This work is developing an automated system to conduct cognitive screening in memory clinics.
I am PI for an Alzheimer’s Research United Kingdom (ARUK-PPG20114B-25) 2014-2016 (£29,805) project: ‘Developing a new biomarker for the early diagnosis of dementia; a novel non-linear signal processing approach using resting state EEG’. This is in collaboration with Dr Ptolemy Sarrigianis in the Department of Neurophysiology.
- Quantitative EEG (using Error Reduction Ratio causality test) can record differences in bi-parietal synchronisation between people with Alzheimer’s disease compared to healthy controls. Alzheimer’s Research United Kingdom (ARUK-PPG20114B-25) 2014-2016 (£29,805).
- Conversation Analysis is a useful technique to detect features that can distinguish between Functional Memory Disorder (FMD) and neurodegenerative dementias.
- Astrocytes play a crucial role in the progression of Motor Neuron Disease. The use of laser capture microdissected astrocytes at different time points from the murine model have shown defects in the normal supportive role- providing cholesterol to neurones as well as an increased immune response. I have now progressed this and with collaborators in SITRAN have produce i-Astrocytes from skin samples of my patients with sporadic AD.

I am co-supervisor of Jenna Littlejohn with Professor Venneri. This project started in October 2014 and is investigating deafness as a risk factor for dementia.

- I am a module leader the MSc in Clinical Neurology
I completed my undergraduate medical degree in Liverpool in 1998 and did my medical training in London. I have worked as a neurology SpR in Singapore and Nottingham prior to joining the University of Sheffield as a PhD student in 2005. I worked as a clinical lecturer in neurology from 2010-2013 and started as consultant neurology in 2013 before taking up my Senior Lecturer post in 2017. My main subspecialty interest is in dementia.
I am co- module leader on two parts of the MSc in Clinical Neurology and lead the research projects module. I helped set up this MSc and develop the curriculum and teaching components. I teach undergraduate medical students.
