Research

My main research interest is the area of statistical inference in molecular evolution for phylogenetics, as well as in inference for trait evolution. One of my aim is to detect what groups of genes share the same genealogy, and to draw inference on the distribution of genealogies across the genome. This area involves statistical issues of model selection, hierarchical modelling of species genealogies and gene genealogies, and it also involves computational challenges. Indeed, molecular data become available faster than appropriate methods of analysis. Development of these methods is funded by the NSF for application to the tree of Enterobacteriaceae, and to study discordance patterns.

More recently, I have been interested in using phylogenetic trees to analyze trait evolution, using the so-called 'comparative methods'. Data collected on species (or related individuals) do not form a random sample because they lack independence: sister species are expected to have similar traits. Such samples actually show a high level of dependence, and there need to be adapted statistical methods of analysis. I am especially interested in the effective degree of freedom for parameters in these models. See this NSF project.
