# Rüdiger Bieler

Rüdiger Bieler (born 1955 in Hamburg, Germany) is a German-American biologist whose primary scientific field of study is malacology, the study of mollusks.

## Training and career

Bieler studied biology, geography, and biology education at the University of Hamburg (Germany), where he held a scholarship of the Studienstiftung. After extensive field research in South Africa (with Richard Kilburn) he received a PhD (DSc) degree in Zoology in 1985 under Otto Kraus. Following several postdoctoral research fellowships under the mentorship of Richard S. Houbrick and Mary E. Rice (Smithsonian Institution) at the National Museum of Natural History (1985-1986), the Smithsonian Marine Station at Fort Pierce, Florida (1986-1987), and a NATO postdoctoral fellowship (1987-1988, also at the Smithsonian Marine Station), he became Curator of Malacology at the Delaware Museum of Natural History. Since 1990, he is a Curator of Invertebrate Zoology at the Field Museum of Natural History in Chicago (following predecessors Fritz Haas and Alan Solem). He also is a faculty member of the Committee of Evolutionary Biology of the University of Chicago.

## Research

Much of Bieler's taxonomic research work has focused on marine gastropods (sea snails), especially on sundials (Architectonicidae) and worm-snails (Vermetidae). His evolutionary studies first concentrated on Gastropoda and later extended to Bivalvia and included the earliest application of computer-assisted phylogenetic (cladistic) analyses in that group. He was the lead author on a revised classification for all bivalves, see Taxonomy of the Bivalvia (Bouchet, Rocroi, Bieler, Carter & Coan, 2010), and on major work providing a new hypotheses of the branching pattern in the Bivalve Tree of life (biology) based on both morphological-anatomical and molecular data. He serves as an editor for the phylum Mollusca on the World Register of Marine Species (WoRMS) and as a Chief Editor for MolluscaBase.
Bieler led collaborative efforts in molluscan systematics and evolutionary biology supported by the National Science Foundation (NSF) serving as Principal Investigator of Partnership for Enhancing Expertise in Taxonomy, PEET(PEET-Bivalves) and the Tree of Life project. He organized various international scientific symposia resulting in peer-reviewed symposium volumes on molluscan systematics and evolution.
He and collaborators developed a series of International Marine Bivalve Workshops that paired students and early-career faculty with leading scientists during intensive fieldwork experiences, resulting in jointly published peer-reviewed articles in scientific journals.
A regional focus of his work has been on the invertebrate animal diversity of South Florida and the Florida Keys. He is affiliated with The Elizabeth Moore International Center for Coral Reef Research and Restoration of Mote Marine Laboratory. The research concentrates on the development and documentation of baseline data of regional diversity, allowing the recognition of faunal changes due to human impact. Bieler's work in the Florida Keys encompasses an active participation in coral reef restoration efforts, and the survey and monitoring of shipwrecks off the Florida Keys for invasive marine species.

## Honorary appointments

Bieler held honorary appointments with various research institutions, including the Smithsonian Institution, Harvard University, and the American Museum of Natural History in New York. He was elected President of both the American Malacological Society (AMU/AMS, 1996) and the International Malacological Society “Unitas Malacologia” (1995-1998) and organized their congresses in Chicago in 1996 and Washington, DC. in 1998.
Bieler has served as President of the Institute of Malacology (publishers of Malacologia - International Journal of Malacology) and as editor or associated editor for numerous scientific serials, including the Zoological Journal of the Linnean Society. He is a Fellow of the Linnean Society of London. Actively involved in the administration of natural history museums, he served in various roles including Zoology Department Chair (Field Museum, 1998-2002) and Board Trustee of the Delaware Museum of Natural History (1991-1999).

## Exhibitions and publications

Bieler has been a key contributor to several major museum exhibitions, including Pearls, Evolution on the Half Shell and Specimens!. His own work has been featured in permanent museum exhibitions, such as Abbott Hall of Conservation - Restoring Earth, in a book about the curatorial profession, as well as PBS NewsHour and PBS Changing Seas episodes. He has published, alone or in collaboration with others, more than 100 books, monographs, and articles.
