Why are some of the regions on Earth much more species-rich than others? Why are some groups of organisms more diverse than others? Are there traits that make animals and plants speciate faster? How are new species formed? I try to find answers to these questions using mainly phylogenetics and genomics.
Below are some of the projects that I have worked on lately:

Howea palms exchanged genes after they speciated; some genome regions were more likely to be exchanged

Faster rates of seed size evolution across the angiosperm Tree of Life are positively associated with rates of speciation

Colonisation events and not in situ speciation shaped the flora of a small oceanic island (Cocos Island, Costa Rica)
