Reconciliation-based detection of co-evolving gene families
Genes located in the same chromosome region share common evolutionary events more often than other genes (e.g. a segmental duplication of this region). Their evolution may also be related if they are involved in the same protein complex or biological process. Identifying co-evolving genes can thus shed light on ancestral genome structures and functional gene interactions.
We devised a simple, fast and accurate probability method (...)

Evidence de sélection dans le génome humain : adaptation polygénique et fardeau d’expansion
Les populations humaines ont connu une expansion hors d’Afrique dans les 50,000 dernières années qui a certainement nécessité des adaptations au niveau génétiques, mais qui ont aussi pu avoir des conséquences sur leur fitness. Dans cette conférence, je présenterai nos travaux récents sur l’identification de sélection polygénique au niveau de voies métaboliques chez l’homme, ainsi que sur l’accumulation potentielle (...)

Dating phylogenies with incompletely preserved fossils
In recent years, evolutionary biologists have become increasingly interested in dating phylogenies. This is usually accomplished by calibrating interior nodes in the tree against the fossil record, an ad hoc approach with a considerable risk of mirepresenting the fossil information. I discuss an alternative approach, in which fossils are included along with extant taxa in a Bayesian total-evidence analysis. By coding morphological (...)

Non-random inbreeding with respect to phenotype biases estimates of inbreeding depression
Animals often show substantial variation in dispersal behaviour and resident individuals are more likely to inbreed. At least part of the variation in dispersal behaviour may be phenotype-dependent, potentially leading to non-random inbreeding with respect to a particular phenotype. Here we show that non-random inbreeding in structured populations can have important implications for estimates of the (...)
