Research area : Molecular evolution, molecular phylogeny, population and evolutionary genomics, bioinformatics.
Associate Editor : Journal of Molecular Evolution, Biology Direct, Faculty of 1000
Big questions I would like to answer (eventually) :
Why are fast-evolving genomes fast ?
Does population size matter ?
Why is mitochondrial DNA hypermutable in (most) animals but not in plants ?
How much does GC-biased gene conversion impact functional genome evolution (in human) ?
Should you build trees in case of horizontal gene transfer, and how ?
