Core Team


Professor Brian Brown, Emeritus Professor of Medical Physics

Professor Brown has had a life-long career researching of bioimpedance and its clinical application. Being a world authority with several hundred publications to his credit, his work informs the device prototype for cervical cancer screening, currently being evaluated in EU-wide clinical trials. He holds several EIS patents.

Dr Graham Stafford, Senior lecturer in Microbiology (non-clinical)

Graham is a Senior Lecturer in microbiology based in the Dental School in Sheffield. He gained a PhD (Warwick) in 2002 before spending five years at Cambridge. He is the lead researcher for the microbiome sub-study within Ecclippx where cutting edge DNA sequencing approaches are being used to examine if there is a microbial signature associated with risk of pre-term birth which could contribute to improved diagnosis.

Professor Stephen Walters, Professor of Medical Statistics and Clinical Trials

Professor Stephen Walters is a medical statistician with over 20 years’ experience of designing, analysing and reporting the results of a variety of studies including, randomised controlled trials, observational studies and surveys. He has over 220 publications (including 133 in refereed journals and 3 books). He has been a co-applicant, statistical advisor and collaborator on numerous health services research projects (over 50 funded projects with a total value of £27.1 million). Stephen will be involved in the statistical analysis and reporting of the diagnostic accuracy data from the Electrical Impedance Spectroscopy (EIS) device to predict pre-term birth.

Professor Simon Dixon, Professor of Health Economics

Professor Dixon is Health Economist with vast experience evaluating the cost-effectiveness of health care interventions in large clinical trials.

Professor Anthony T Barker , Prof. Associate, University of Sheffield Medical School

Tony recently retired from the U.K. National Health Service after 38 years in the Sheffield Department of Medical Physics and Clinical Engineering. An engineer by training, he has specialised in a number research areas during his NHS career, including the effects of electromagnetic fields on the body (both detrimental and therapeutic), electrical stimulation of nerves, Functional Electrical Stimulation and medical device development. Tony led the group which invented the technique of Transcranial Magnetic Stimulation, now widely used throughout the world for basic research, diagnosis and therapy, and also the group which developed the first self-optimising, array based FES stimulator for foot drop. He has sat on numerous professional committees and, for 25 years, chaired the Biological Effects of Low-Level Electromagnetic Fields Policy Advisory Group of the Institution of Engineering and Technology. Tony has an active interest in the public understanding of science and has given many named and public lectures including the Faraday lecture series, the Silvanus P Thomson series and a Royal Institution Discourse.
