Professor Williams is currently Professor of Health Services Research and Consultant Gastroenterologist at Swansea University’s College of Medicine. From 2002 - 2007 he was Wales Director of Research and Development, a post in which he established the Clinical Research Collaboration in Wales.

Professor Williams’ main research interests are gastroenterology, health services, health informatics, service delivery, and patient outcome. He chiefly focuses on better diagnosis, treatments and services - particularly in gastroenterology - and on increasing patient involvement in these processes.  He has researched novel means of outpatient services delivery and changing roles in gastrointestinal endoscopy. He is presently Chief Investigator of a large trial in ulcerative colitis, and a member of the National Institute for Health Research Health Services Research Board.

Professor Williams has a long-standing interest in improving information systems that support patient care, and directs the Royal College of Physicians’ Health Informatics Unit. He has evaluated usage of routinely collected data to support research, audit and professional appraisal, highlighting the need - from a clinical perspective - for standardising the structure and content of patients’ records. At the Royal College of Physicians, he has led the development of evidence- and consensus-based standards for hospital admission records and communications.  This work was supported by NHS Connecting for Health, with established standards endorsed by the Academy of Medical Royal Colleges.

Professor Williams presently chairs a UK Clinical Research Collaboration Board subgroup working to raise public awareness of the benefits derived from using patient data in research. Professor Williams is a member of the OSCHR e-Health Board, and, in 2014, received a CBE for services to medicine.
