Catherine Legrand
Professeure ordinaire
Catherine Legrand obtained a Master Degree in Mathematics from the Université Libre de Bruxelles (ULB) in 1998. Before embracing an academic career, she worked for 7 years at the European Organization for Research and Treatment of Cancer (EORTC, Brussels) as the primary statistician of the EORTC Lung Cancer Group. She was also a member of the Treatment Outcome Research Group, the Elderly Task Force, and coordinator of the EORTC Independent Data Monitoring Committee (IDMC). She was involved in the design, monitoring, and analysis of numerous clinical trials. In parallel, she completed a PhD in 2005 at the Center for Statistics, UHasselt, developing new methods based on the frailty model to investigate heterogeneity in cancer multi-center clinical trials. Early 2006, she started working as biometrician at Merck Sharp & Dohme (MSD, Brussels) where she was involved in the design and analysis of clinical trials in respiratory diseases and HIV. Since September 2007, she is full time Professor at the Institute of Statistics, Biostatistics and Actuarial Sciences (ISBA) of the Université catholique de Louvain (UcL), teaching statistics and biostatistics to bachelor and master students.
