Tree of life is one of the most ambitious and compelling project in the lifescience: it strives to disentangle patterns of relatedness among living things – i.e. to resolve their phylogeny. While studies on some animal lineages, especially those attracting broad public attention, like birds and mammals are well on their way, other groups are often neglected, despite their abundance, ecological and economic significance. In this project I will use various types of high throughput sequencing data (targeted enrichment, RNA-Seq) to address relationships in the hyperdiversified, yet still poorly studied molluscan class Gastropoda, focusing on several key radiations. Among these, I already have large dataset for the order Neogastropoda, and envision expanding to the superfamily Pyramidelloidea in the nearest future.
