My research uses genome-wide data to reconstruct the history of species and clades. Using population genomic and phylogenomic methods, I have studied how past climate and landscape changes have affected the distribution and demography of tropical taxa.
This work has investigated population size shifts, range expansions, gene flow, and the timing of population coalescence in rainforest lizards (Anolis and Polychrus).
These results support that faunal interchange among major biomes was essential to the assembly of tropical biotas, challenging a simple model of in situ diversification. Moreover, this work suggests that ecology and phenotypes attenuate or exacerbate the impact of habitat fragmentation on co-distributed organisms.
