The main motivation behind my research is to understand the origins of biological diversity. My research focuses on inventorying biodiversity and unveiling the processes that shape temporal and spatial dynamics of life. I study biological evolution in a phylogenetic framework, boosting traditional natural history approaches with modern molecular tools to infer genealogical information, delimit species and accelerate biological inventories. I conduct most of my research on isolated ecosystems (e.g. islands, caves, mountain tops), which provide test-tube like conditions for the study of evolution, and use spiders as model organism.
