Team 

Populations, Statistics and Genome (PSGen)

Fields of research

Methodological development for high-throughput genomic data, mainly transcriptomic (microarray and RNA-seq): differential analysis and gene network inference. Mixed models (linear, non linear and generalized linear models), stochastic EM algorithm, heterogeneous variance modelling, longitudinal data analysis (covariance structure modelling).
