Phylogenomics
To infer macroevolutionary processes, we infer relationships of invertebrates using genome-scale datasets. These datasets span transcriptomes, mitogenomes, ultraconserved elements, target-capture of conserved exons, and whole genomes. Recent projects in the lab have focused on the internal phylogeny of groups like scorpions, sea spiders, and Chelicerata as a whole.

We use these phylogenies as the framework upon which we reconstruct macroevolutionary phenomena, like the evolution of arthropod appendages.
