I am a plant systematist and am broadly interested in the investigation of the patterns and processes that shape plant biodiversity. In general, my research is focused on the use of molecular methods to reconstruct phylogenetic relationships in plants and the application of phylogenetic methods to understand plant evolution. The evolutionary causes and consequences of processes such as hybridization, polyploidy, pollination biology, biogeography, rapid diversification, and niche evolution can only be understood in light of a robust phylogenetic hypothesis, and these hypotheses are a necessary component of modern taxonomic treatments and classification systems. Research in my lab is directed at multiple levels of plant phylogeny and current projects range from comparative phylogeography of the Pacific Northwest inland rainforest communities, to the study of species boundaries and diversification among very closely related species, to patterns of diversification among some of the major lineages comprising the plant tree of life.
After receiving his Ph.D. from the University of Washington in 2006, David moved to a postdoctoral position in the Peabody Museum of Natural History and Department of Ecology and Evolutionary Biology at Yale University before joining the faculty at the University of Idaho in 2008. David's research is focused on the use of molecular methods to reconstruct phylogenetic relationships in plants and the application of these methods to the investigation of the patterns and processes that shape plant biodiversity, as well as our modern taxonomic treatments and classification systems. Research in Dr. Tank's lab is directed at multiple levels of plant phylogeny and current projects range from comparative phylogeography of the Pacific Northwest inland rainforest communities, to the study of species boundaries and diversification among very closely related species, to patterns of diversification among some of the major lineages comprising the plant tree of life.
In addition to Dr. Tank's phylogenetic research program, he is also the Director of the University of Idaho Stillinger Herbarium – a collection of over 200,000 specimens that represents an archive of the diversity of Idaho's vascular plants, nonvascular plants, lichens, and fungi through space and time. The collection supports research in floristics, systematics, evolution, ecology, and conservation, providing valuable documentation of the changes to our flora as we are faced with human environmental impacts, land use changes, and a changing global climate.
