Dr John Barbur

Dr John Barbur, Consultant Diabetes Specialist, combines fundamental vision science with applied and clinical research, which underpins a long record of research achievement and wider impact. Work on camouflage for the Royal Signals and Radar Establishment led to insights into the processing of luminance and colour signals that have important applications in colour vision assessment. New research instrumentation and measurement techniques have led to new methods for investigating mesopic vision, instrumentation for pupillometry, eye movements, spatial and chromatic vision, and also the effects of scattered light in the eye. The P_SCAN system makes binocular measurements of pupil size and eye-movements and has been used throughout the world for two decades. The P_SCAN system enabled the discovery of new components of the pupil response that require the processing of stimulus attributes such as colour or motion in central areas of the visual cortex. The system made possible studies on ‘Blindsight’, many of which were carried out with MRC support. These studies led to the formation of the Centre for Applied Vision Research (CAVR) at City University.

As a Fulbright Scholar, John worked as a Visiting Professor at the Center for Visual Science at the University of Rochester, N.Y. This work led to studies of mesopic vision supported by DTI (scales for the mesopic range), the EU (Mesopic Optimization of Visual Efficiency) and the DfT (medical aspects of fitness to drive). This was followed by EPSRC grants on “Minimizing Glare in Lighting Installations” and “Mesopic Optimization of Residential Street Lighting”. These studies supported the development of several Advanced Vision and Optometric Tests (AVOT), initially for research studies and later for more precise assessment of vision in visually-demanding environments such as aviation and rail transport.

The CAD (Colour Assessment and Diagnosis) is now used throughout the world to assess pilots, air traffic controllers, firefighters, seafarers, police officers and more. The AVOT tests are marketed by a City University spin out company, and have applications within ophthalmology, vision-related clinical trials and visually demanding occupations. Significant laboratory refurbishments carried out during the past few years and sponsorship for projects designed to promote industrial and clinical applications of vision research strengthened the CAVR which is now internationally recognised as a leading centre in visual psychophysics and colour vision studies.

Dr Ellen Fallows, BMBCh, BA(oxon), MRCGP

Ellen is a GP partner and the Diabetes Lead in her practice in Oxfordshire. Her interest in lifestyle medicine comes from having seen a number of her patients put their chronic diseases into remission with primary care supported lifestyle-change.

With a foundation in evidence-based medicine from Oxford University, she is active in primary care research at her practice, including trials using low carbohydrate/low calorie diets to treat hypertension, obesity and diabetes as part of the DROPLET and DIAMOND studies. She has just started a GP Fellowship to research the effectiveness of group consultations for diabetes care with the support of Professor Fraser Birrell.

Ellen is passionate about improving education in the area of lifestyle medicine both for patients and health care professionals. She is working with her local council and CCG to deliver the aims of “Bicester Health New Town”. As part of this initiative, she has helped deliver large-scale education sessions for patients on the role of exercise and diet in diabetes but also COPD. She is one of the first GPs in her area to start Group Consultations, train a practice “social prescriber” and to support her surgery to become a Park Run practice.

She is working to bring together like-minded health professionals in Oxfordshire to learn about motivating, evidence-based lifestyle interventions. She believes that lifestyle medicine can save GPs from burn-out by empowering all of us to live healthier lives; being part of the BSLM is a great way to spread the word!

Dr Tim Young

Dr Tim Young is a Consultant Neurologist with over a decade’s experience as a headache specialist in London. He also currently works as course tutor for the UCL Clinical Neurology by distance learning MSc/Diploma courses in Queen Square, teaching doctors worldwide. He obtained a BSc in Biomedical Science, then qualified top in Medicine with distinction in 1997, before being awarded his PhD in Neuroscience from Imperial College London in 2009. He still works as a consultant neurologist in London, having fellowships both in clinical work (FRCP) and education (SFHEA), and has given numerous invited lectures and authored many articles, with headaches a key theme.

Almost every day in the UK around 100,000 people miss work or study because of headaches, often without even having a diagnosis, let alone a treatment plan. After seeing so many patients over the years who had not sought help for their migraines for years until their sick leave became excessive, Dr Young sought to help support companies with their care for employees impacted by headaches. This lead to the formation of the company ‘Young Headache Management’ in 2017. The key is to empower dedicated Occupational Health and Wellbeing teams with the specialist knowledge required to further help headache management in the workplace. Such approaches can help affected employees-helping also to reduce sick leave and lost productivity as a result. Options range from simple lectures to more in-depth workshops.
