Frits Rosendaal is professor of Clinical Epidemiology at the Leiden University Medical Center. He has a long standing track record in research in thrombosis and haemostasis, with many publications in leading biomedical journals. He designed several studies, such as LETS and MEGA,  that were instrumental in the identification of a series of risk factors for thrombosis, which ranged from genetic factors to environmental ones, particularly related to drug safety, such as specific brands of oral contraceptives. In the field of anticoagulant treatment he developed the method used to estimate the time in therapeutic range (TTR). In the field of haemophilia, he oversees the Haemophilia in the Netherlands national projects, and is involved in studies of inhibitor development, again in the context of drug safety.
