Research Interests

Dr. Bierner’s research focuses on phylogenetic and systematic studies of flowering plants, in particular members of subtribes Gaillardiinae and Tetraneurinae of the sunflower family, Asteraceae. Dr. Bierner uses data from morphologic, cytologic and molecular studies to define the taxonomic units within these subtribes (i.e., genera, subgenera, sections, subsections, species, subspecies, varieties) and to better understand their evolutionary histories and present-day relationships. He is currently working on treatments of several genera for the Jepson Manual of Plants of California.
