Professor Roger Williams CBE, runs the Institute of Hepatology at UCL, and is a twice former president of EASL. He has authored an incredible 2100 journal articles. Despite advancing years, he is still actively involved in clinical research–340 articles in the past ten years, and analysis by ISI shows him to be one of the most influential researchers in his field. The award of a CBE for services to medicine recognised his major contribution to the study of liver disorders over 25 years including leading the team who performed the first ever liver transplant in the UK. Prof Williams has had many awards, medals, honorary fellowships, and in 2006 was included by HRH The Queen in a celebration at Buckingham Palace to honour those who continue to contribute to public service beyond the age of 65yrs. He was made a Fellow of King's College London in 1992 and an Honorary Fellowship from UCL was conferred on him in 2008, in recognition of his distinguished career and outstanding service to UCL.
