Lisa Pape, secretary
Professor Michael Laffan trained in medicine at Oxford University and in haematology at the Hammersmith and Royal Free hospitals in London. He returned to the Royal Postgraduate Medical School, then based at Hammersmith Hospital, as a consultant in 1992. He has been director of the Hammersmith Hospital Haemophilia Centre since that time. He has published extensively on blood coagulation and recently edited the 12th edition of Practical Haematology. Professor Laffan is chair of the British Society of Haematology Task Force on Haemostasis and Thrombosis and Chair of the UK Bleeding Disorders study group. He recently completed six years as secretary of the United Kingdom Haemophilia Centre Doctors’ Organisation (UKHCDO). He is a fellow of the Royal College of Physicians and a fellow of the Royal College of Pathologists.
Hereditary and acquired bleeding disorders, thrombosis, anticoagulation, antiplatelet therapy
Research & publications
Professor Laffan’s research interest is centred on von Willebrand disease and the function of the von Willebrand factor molecule. He also has interests in mechanisms of thrombin generation and the effects of coagulation on blood vessel function. He is a principal investigator in several clinical trials including gene therapy.
