Endocrinology and Diabetes Consultants
Professor Stephen Bloom Steve Bloom is the Head of Division for Diabetes, Endocrinology and Metabolism, Chair of the Academic Section of Investigative Medicine at Imperial College London and Chief of Service for Pathology at Imperial College Healthcare NHS Trust. He heads a 40 strong research team investigating the physiology of regulatory peptides in CNS and periphery.
Professor Bloom received his undergraduate medical training at Cambridge University. His house officer, senior house officer and registrar posts were largely undertaken at The Middlesex Hospital where he also received his MRC Clinical Research Fellow training. He moved to the Royal Postgraduate Medical School at Hammersmith Hospital in 1974 where his roles have included Senior Lecturer (Consultant Physician), Reader in Medicine, Chairman of the Higher Degrees Committee and Academic Board, Professor of Medicine (Honorary Consultant Physician), Director of the Endocrinology Clinical Service and Deputy Director, Department of Medicine, Director of Chemical Pathology (renamed Metabolic Medicine and later Investigative Medicine), Chief of Clinical Service Chemical Pathology and Chief of Service Endocrinology and Diabetes.
His research work over the years falls into five related categories: Endocrinology clinical research, physiology and pathology of gut hormones, control of insulin release and insulin resistance, role of neuropeptides in organ control and the role of neuropeptides in CNS regulation of appetite and related hypothalamic functions. He currently leads a research group investigating hypothalamic appetite control systems and gut hormones. This group’s discovery that oxyntomodulin reduces appetite offers a potential new treatment for obesity and in 2005 Steve co-founded spin out company ‘Thiakis Ltd’ to commercialise these findings.
In the past Steve has been a member of the Main Scientific Board for AstraZeneca and advisory boards for Upjohn and Novartis. He has published over 1000 papers (excluding review articles) in journals such as Nature, J Biol Chem, PNAS, JCI and NEJM.
Professor Waljit Dhillo Professor Waljit Dhillo is a Professor in Endocrinology & Metabolism and Consultant Endocrinologist.
He completed his medical training at St Bartholomew's Hospital Medical School, University of London in 1994. During this time he also completed an Intercalated BSc in Biochemistry (awarded First Class Honours) funded by the Medical Research Council. He then completed his general medical training in London Hospitals. In 1997 he joined the North West Thames Rotation in Diabetes and Endocrinology as a Specialist Registrar. During this time he completed a PhD on the area of novel neuropeptides regulating appetite as a Wellcome Trust Clinical Training Fellow at Imperial College with Professor Sir Steve Bloom. In 2004 he was awarded a National Institute for Heath Research (NIHR) Clinician Scientist Fellowship and appointed Clinical Senior Lecturer & Consultant in Diabetes & Endocrinology at Imperial College London. Following this he was awarded an NIHR Career Development Fellowship and promoted to Reader in 2009. In 2011 he was promoted to Professor in Endocrinology & Metabolism. In 2015 Professor Dhillo was awarded a prestigious NIHR Research Professorship.
Professor Dhillo's research investigates novel aspects of endocrine control of obesity and reproductive function. His research has focused on understanding the neuroendocrine mechanisms which are important in the regulation of food intake. The regulation of body weight is complex and requires control of both food intake and energy expenditure. Gut hormones can powerfully reduce appetite and increase energy expenditure. Professor Dhillo's research investigates the mechanisms by which gut hormones mediate their effect. Recently he has shown that administration of gut hormones to human volunteers can alter neuronal activity in brain reward areas which control food intake (http://www.guardian.co.uk/science/2011/sep/11/obesity-food-appetite-suppressant). He was awarded the Royal College of Physicians Linacre Medal for this work. These findings have identified CNS pathways which have potential as novel targets for the development of anti-obesity drugs.
Professor Dhillo's recent translational research has identified the novel hormone kisspeptin as a potential novel therapy for infertility. Professor Dhillo has carried out the 'first time into human' studies of kisspeptin. He has shown that kisspeptin potently stimulates reproductive hormone release in human male and female volunteers. This work was awarded the American Endocrine Society Award for Excellence in Clinical Research and the British Society for Neuroscience Investigator Prize. Professor Dhillo has also shown that kisspeptin administration potently increased reproductive hormone release in women with infertility due to hypothalamic amenorrhea (http://www.bbc.co.uk/radio4/womanshour/04/2009_11_tue.shtml). Recently Professor Dhillo has shown for the first time in women with infertility that kisspeptin can be used safely and effectively in IVF treatment http://www.bbc.co.uk/news/uk-england-london-22953488. He was been awarded the Royal College of Physicians Goulstonian Lectureship (2010) and the Society for Endocrinology Medal (2015) for this work.
Professor Des Johnston Professor Des Johnston trained in Edinburgh and Southampton where, as an MRC Training Fellow, he did his PhD with Professor George Alberti. His work at that time investigated metabolic disturbances in liver disease and metabolic aspects of endocrinology. He moved subsequently to Newcastle where he obtained a Wellcome Senior Clinical Research Fellowship, investigating metabolism in diabetes. In 1986, he was appointment to the Chair of Clinical Endocrinology at St Mary’s Hospital Medical School and the Royal Postgraduate Medical School, which became part of the Imperial College School of Medicine in 1996. He was appointed Dean (Clinical) of Imperial College London in 2004 and in 2006 he was appointed Campus Dean for the St Mary’s campus of Imperial College. His major interests currently are in the pathogenesis of type 2 diabetes. He is investigating early metabolic changes which are observed in people predisposed to develop type 2 diabetes, but before the onset of the disorder. The rationale of this approach is that such early changes may represent primary abnormalities which are causative. In July 2005, he was appointed Director of the UK Diabetes Research Network.
