David is a vertebrate paleontologist interested in how functional traits influence macroevolution. His focus is on mammals from the Mesozoic Era. His Masters degree at Indiana University was on the diversification of mammal molars in response to the Cretaceous Terrestrial evolution, co-advised with Jackson Njau. He went on to complete a PhD at University of Chicago with Zhe-Xi Luo and Ken Angielczyk, and later worked with Greg Wilson at University of Washington.
