Amanda Lewis

Dr Amanda Lewis, Senior Trial Manager

Amanda is currently a Senior Trial Manager at the Bristol Randomised Trials Collaboration unit, part of the Bristol Trials Centre. She joined the department in 2014 as Trial Manager for the UPSTREAM trial, which focuses on the diagnosis and management of bladder outlet obstruction for men in 26 hospitals in England. Amanda also provides day-to-day operational management, and senior oversight and support for several NIHR-funded multi-centre RCTs (RELIEF, PURSUIT, and STRATA). These trials take place across a range of research themes in various settings (e.g. secondary care urology and urogynaecology units, Emergency Departments (A&E), and Mental Health Services) and in differing population groups (e.g. men with lower urinary tract symptoms, women with recurrent stress urinary incontinence, older adults with rib fractures needing urgent care, and adults with a diagnosis of autism and anxiety). Outside of work, Amanda enjoys the great outdoors, music (classical in particular), and photography.

Doug Webb, Trial Manager

Doug is a Clinical Trial Manager with experience in the delivery of clinical research in the areas of mental health, neurology, dermatology, and metabolic disease. He is based within the Bristol Randomised Trials Collaboration, part of the Bristol Trials Centre, and is excited to be managing the STRATA trial. As a keen outdoor enthusiast in his spare time, you will most likely see him hiking in the mountains or at his local parkrun (he does enjoy a coffee, cake, and a chat too)!
