Dr Michel Vaillant


Dr Michel Vaillant has a background in Biology, Statistics and Epidemiology from the Universities of Montpellier and Bordeaux, France. He joined LIH in 2003 after 5 years in a contract research organisation for the pharmaceutical industry as Data Manager and Statistician (1998-2003), a short journey in an epidemiological consulting office (1997) and a 2 years stay in the International Research Center of Franceville in Gabon (1995-1997).

He has applied up-to-date statistical methods to different clinical and epidemiological studies from analysis of variance to linear mixed models or generalized mixed models in the field of neurodegenerative diseases such as Parkinson’s and Alzheimer’s.

He has developed collaborations with partners acting in Poverty Related Infectious Diseases. With a strong background in Malaria epidemiology and clinical trials, Michel has been project leader for the data management and statistics aspects of 3 large clinical trials (≈ 3400 patients) with WHO/TDR.

Michel teaches clinical research, public health and research methods at the University of Metz and participates in the WHO/TDR capacity building programme, which allows African visiting scientists to be trained.

Head of unit

Michel Vaillant, MS in statistical methods, MS in epidemiology, PhD in epidemiology/biostatistics, is the CCMS head of unit since april 2018 after retirement of the former Head, Prof Stephen Senn. He was deputy head of unit since 2013. He has past experience in research in Africa (1995-1997), epidemiology (1997), contract research organisation for pharmaceutical industry (1998-2003) and is with LIH since 2003 first as the single biostatistician in the institution. The unit has now grown up to 9 members.
