The team develops new models and statistical methods for data from epidemiological studies and clinical trials, with a strong emphasis on cohort data analysis.
Objectives
The Biostatistics team develops statistical methods for the analysis of data from epidemiological studies or clinical trials. The major area of research focuses on dynamic models, i.e. all the models to take into account the temporal dimension of events and processes. Some works have a strong theoretical dimension but they are all motivated by applications for natural history, risk factors, diagnosis or prognosis of chronic diseases such as Alzheimer’s disease, AIDS, cancer or disease chronic kidney and by the assessment of the impact of these diseases for Public Health. Software that implements these methods are regularly made available to the scientific community via Internet. To support its activities recruitments are planned.
