Professor Williams is currently Professor of Health Services Research 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 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, and has led multicentre trials in inflammatory bowel disease.  He has evaluated the use of routinely collected data to support research, audit and professional appraisal, highlighting the need for improvement in the quality of the data recorded in patient records and clinical communications.

From 2001 to 2019 Professor Williams led Health Informatics at the Royal College of Physicians where he drove the development of consensus based national standards for the structure and content of patient records and communications.  This work is now being taken forward by the Professional Record Standards Body, which he was instrumental in establishing.  He also drove the creation of the Faculty of Clinical Informatics, of which he is a founding fellow.

In 2014 Professor Williams received a CBE for services to medicine.
