Nicolas GALTIER
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?
