Dr. David Grimaldi's research is broadly concerned with the evolution of insects, from species-level diversity in drosophilid fruit flies to the phylogeny of orders over the past 400 million years. The research relies on fieldwork collecting recent species and excavating new deposits, exploratory morphology, study of insect fossils, and phylogenetics. A major research project at present includes the relation between the radiations of insects and angiosperms in the Cretaceous. Another major project is on a diverse deposit of Triassic insects from Virginia, the only such deposit in the Western Hemisphere. Ongoing research explores the diversity and biogeography of a Miocene community preserved in amber from Hispaniola.For more interviews, visit our "Meet the Scientists" channel:http://www.amnh.org/explore/amnh-tv/(category)/1325
