Daniel Graf


Daniel Graf joined the Department of Biology at UW-Stevens Point in 2012. His teaching and research interests involve freshwater malacology, bivalve systematics, the methodology of the phylogenetic systematics, and biodiversity informatics. His Ph.D. dissertation was “A Phylogenetic Perspective on the Evolution of the Unionoida (Mollusca Bivalvia Palaeoheterodonta): Using Pattern to Test Hypotheses of Macroevolutionary Process.”

For the last few years, Graf has focused on tropical freshwater mollusks, especially the freshwater bivalves of Africa, and the post-glacial distributions of freshwater mussels in North America. Graf manages the online MUSSEL project funded by the National Science Foundation, a searchable database of freshwater mussels of the world. In addition he has gathered an online freshwater invertebrates of Wisconsin website at
