Research Interests

My main research focus is on the development of new techniques to diagnose and monitor neuromuscular disorders. I use a variety of electrophysiological techniques in both pre-clinical and clinical settings in order to better understand how these diseases start and change over time.     

Current Projects

  • Use of the motor unit number index (MUNIX) and the motor unit size index (MUSIX) to monitor disease progression in motor neurone disease
  • Use of different types of spectroscopy to monitor neuromuscular disease
  • Phenotyping preclinical models of MND


My work is or has been supported by the following:

  • Medical Research Council
  • Academy of Medical Sciences
  • Motor Neurone Disease Association
  • Engineering and Physical Sciences Research Council
  • Ryder Briggs Neuroscience Research Fund
  • Neurocare

2018 – Present

Senior Clinical Lecturer in Neurophysiology, University of Sheffield

Honorary Consultant Clinical Neurophysiologist, Sheffield Teaching Hospitals NHS Foundation Trust

2015 – 2018:

NIHR Academic Clinical Lecturer in Neurophysiology, University of Sheffield

2012 – 2014:

Specialty Registrar in Clinical Neurophysiology, Yorkshire and the Humber Deanery

2010 – 2012:

NIHR Academic Clinical Fellowship in Core Medical Training/Neurology, University of Sheffield

2008 – 2010:

2000 – 2008:

MB/PhD programme, University of Leicester Medical School


I studied medicine at Leicester Medical School, undertaking an intercalated BSc in neuroscience (1st class Hons). I then entered the MB/PhD programme, completing a PhD on the molecular mechanisms of perinatal white matter injury. After graduating I completed academic foundation programme training in London before coming to Sheffield to take up an NIHR academic clinical fellowship in neurology. I subsequently moved into clinical neurophysiology and completed the final part of my training as an NIHR clinical lecturer.

Teaching Interests

I am module leader for the Applied Neuroanatomy & Clinical Neuroscience module on the MSc Neurology course. I am also the Deputy Director of Studies for Phase 3a of the medical degree.

I regularly give neurophysiology lectures and demonstrations to medical and postgraduate students. I also provide research supervision to PhD students, intercalating medical students, MSc students and supervise students on SSC attachments. I am also a personal and academic (PATS) tutor for medical students.

I am particularly keen to encourage medical students to undertake research during their time at medical school and welcome any enquiries regarding potential projects.
