Introduction
Given the current biodiversity crisis we are facing, stemming from anthropogenic climate change, it is vital we improve our understanding of the mechanisms driving the origin and maintenance of biodiversity across spatiotemporal scales. I am a botanist and an evolutionary biologist, and I implement HTS approaches (Hyb-Seq) and large-scale phylogenetic analyses (phylogenomic workflows on HPC architectures) to bridge evolutionary scales and to unravel biogeographic patterns, mostly in land plants.

The reduced cost of high‐throughput sequencing and the development of gene sets with wide phylogenetic applicability has led to the rise of sequence capture methods as a plausible platform for both phylogenomics and population genomics in plants. An important consideration in large targeted sequencing projects is the per‐sample cost, which can be i...
Article
Full-text available
Angiosperms are the cornerstone of most terrestrial ecosystems and human livelihoods1,2. A robust understanding of angiosperm evolution is required to explain their rise to ecological dominance. So far, the angiosperm tree of life has been determined primarily by means of analyses of the plastid genome3,4. Many studies have drawn on this foundation...
Article
Full-text available
Reconstructing evolutionary trajectories and transitions that have shaped floral diversity relies heavily on the phylogenetic framework on which traits are modelled. In this study, we focus on the angiosperm order Ranunculales, sister to all other eudicots, to unravel higher-level relationships, especially those tied to evolutionary transitions in...

Chapter
Whole genome duplications (WGD) are frequent in many plant lineages; however, ploidy level variation is unknown in most species. The most widely used methods to estimate ploidy levels in plants are chromosome counts, which require living specimens, and flow cytometry estimates, which necessitate living or relatively recently collected samples. Newl...
Article
Full-text available
Giant genomes are rare across the plant kingdom and their study has focused almost exclusively on angiosperms and gymnosperms. The scarce genetic data that are available for ferns, however, indicate differences in their genome organization and a lower dynamism compared to other plant groups. Tmesipteris is a small genus of mainly epiphytic ferns th...
