Tim Pearce is Assistant Curator and Head of Section of Mollusks at Carnegie Museum of Natural History. The mollusk collection is one of the 15 largest in the United States, and boasts more terrestrial and freshwater mollusks from western Pennsylvania and adjacent states than all other museums combined.

Pearce received his PhD (1994) and MSc (1991) in Biology from the University of Michigan. He completed his post-doctoral work on Madagascar’s land snails at SUNY–Stony Brook from 1995–1996, his Master of Arts degree in Paleontology from the University of California–Berkeley in 1988, and his Bachelor of Science in Marine Biology from Evergreen State College in 1979. Prior to his appointment at Carnegie Museum of Natural History in 2002, he was Assistant Curator of Mollusks at Delaware Museum of Natural History from 1997–2001.

Pearce’s research focuses on the ecology and systematics of mollusks, biogeographical, ecological, and behavioral studies on terrestrial gastropods, and the inventory and distribution of land snails and slugs in the eastern US. His current research involves land snail distribution in Pennsylvania (funded by PA Wild Resources Conservation Program), on the Delmarva Peninsula, eastern USA (funded by US National Science Foundation), in Maine (funded by Maine Outdoor Heritage Fund and others), in New York State (funded by NY Biodiversity Research Institute), and in West Virginia (funded by West Virginia Division of Natural Resources). He is also pursuing the biogeography of land snails on islands in the US Great Lakes, systematics of North American land snails, and land snails of Colombia, South America.

Pearce was a contributing author to the books Marine Mollusks of Bermuda (2009) and the American Malacological Society’s text The Mollusks: A Guide to Their Study, Collection, and Preservation (2006).

Carnegie Museum of Natural History, one of the four Carnegie Museums of Pittsburgh, is ranked as one of the top five natural history museums in the country.
