Nicolas Alexandre


Nicolas’ research focuses on linking phenotypic variation with genotypic variation and fitness within species for complex, quantitative traits. Through fine-mapping of natural genome-wide variation, he is localizing putatively causal loci segregating as polymorphisms that underlie phenotypic variation for bill shape which can be subsequently tested for signals of selection. The bills of hummingbirds represent an excellent model for studying adaptive evolution in quantitative traits given their widespread distribution, feasible collection, and recently available genomic resources. To understand how genomic architecture of complex traits evolves in nature, he is implementing a combination of genome-wide association studies, niche modelling, pollen metabarcoding, functional experiments, and phylogenetic analyses to understand the link between evolution of complex traits within and between species.
