Daniel’s Ph.D. research focused on choanoflagellates, a group of globally distributed marine and freshwater heterotrophic unicellular eukaryotes. He is currently a postdoctoral fellow at the Station Biologique de Roscoff in France, where he has extended his research on choanoflagellates to include the breadth of unicellular eukaryotic diversity as part of the Tara Oceans Project. They have collected surface ocean samples from 150 globally distributed sites at two depths and multiple size fractions, spanning a range from viruses to the smallest animals.  Daniel is analyzing three types of sequence data to examine how species distributions and their global patterns of activity help define the ecology of the world’s oceans.
