I am a molecular systematist working on the phylogeny and evolution of species diversity in insects. My specific interest is the order Coleoptera (beetles), the arguably largest radiation of animal species on Earth, which I use as a model for an evolutionary understanding of the great diversity of living organisms. I apply genomics and phylogenetic analysis, working at all hierarchical levels, from populations to basal relationships of insect orders. Novel high-throughput sequencing methods are constantly opening up new avenues for studying taxonomy and biodiversity, in particular in poorly known groups of arthropods, such as the tropical forest canopy or the soil. Metagenomic shotgun sequencing permits the study of entire complex communities in bulk for the analysis of species richness and phylogeny directly from an environmental sample (‘soup-to-tree’). Equally, we are using environmental DNA (eDNA) and qPCR or metabarcoding approaches to characterize complex communities from soil and water in freshwater habitats, or to study gut content of insects and mammals. I have a joint appointment with the Natural History Museum (NHM) London where I conduct most of my research.
