Research Summary

My research integrates discoveries and data from multiple fields to determine the factors that have shaped marine biodiversity on scales outside human observation (macroevolution).

My unit seeks to determine the origins of modern biodiversity and ecosystems (marine and freshwater), and understand how species respond to big challenges - living and environmental, gradual and sudden, local and global.

This work involves analyses of immense databases for fishes (half of vertebrate diversity) and early vertebrates (half of vertebrate history), as well as detailed, species-level surveys of living and fossil ecosystems in order to tease apart the origins of the life as we know it.
