Gastropods (snails, limpets and slugs) are arguably the most diverse group of animals in the oceans today, with main lineages having diverged hundreds of millions of years ago. I use an array of sequencing and inference methods to resolve gastropod relationships at different levels: from ancient divergences between major gastropod lineages (Cunha & Giribet 2019 Proceedings B), to divergences between subfamilies and genera (Cunha et al. 2019 MPE), while also investigating what biological and systematic sources of error cause conflict between genes and analyses in genomic-scale datasets (Cunha, Reimer & Giribet 2021 Syst Bio).

Collaborations on other diverse groups of invertebrates (e.g. placement of horseshoe crabs within a paraphyletic Arachnida; resolution of the chiton phylogeny) lead to a better understanding of the animal Tree of Life.
