Research Summary
We are broadly interested in how global events, environmental change and ecological interactions affect long-term evolution (macroevolution) in early vertebrates (half of vertebrate history) and ray-finned fishes (half of vertebrate diversity).

Research Interests
Macroevolution, Macroecology,
Early Vertebrates, Ichthyology 
Mass Extinction, Phylogenetics
Biomechanics, Evo-Devo
