Sallan Lab @ Penn
My lab investigates how environmental change, global events, and ecological interactions shaped biodiversity on scales outside human observation (macroevolution/macroecology).
We seek to determine the origins of modern biodiversity and ecosystems (marine and freshwater), and understand how species respond to big challenges - both living and environmental, both gradual and sudden.
This work involves 'Big Data' analyses of immense global 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 diversity.
