Current Research Interests

Sally E. Walker is a Professor of Paleontology at the University of Georgia in Athens, Georgia, USA, and is a specialist in fossil forensics (taphonomy and paleoecology).  She is most interested in how biological, physical and chemical factors affect the preservation of marine organisms in modern and fossil deposits (this includes dissolution of carbonate, effects of predation or ice scour on shell integrity, and the effects of encrusting and bioeroding organisms on preserving or destroying carbonate shells).  Currently, she is working with Ph.D., M.S. and undergraduate students on three projects:  1) The Antarctic Scallop, Adamussium colbecki, as an ecosystem engineer; 2) Taphonomy and paleoecology of the biota within the middle Cambrian Conasauga Formation; and 3) the Middle Miocene Climatic Optimum.  She is a founding member of the Shelf-Slope Experimental Taphonomy Initiative (SSETI) that is an on-going research initiative focused on the preservation and/or destruction of various types of carbonate (crustacea, molluscs, echinoderms) and wood experimentally-deployed along shallow shelf to deep-sea depths in the Gulf of Mexico and Caribbean. She is most known for her work doing field experimental taphonomy in marine systems, which she modeled after Dr. Anna Kay Behrensmeyer's terrestrial work in Africa.  Dr. Walker is a Fellow of the American Association for the Advancement of Science (AAAS), a Paleontological Society Fellow, a Fellow of the Explorers Club and has an Antarctic Service Medal (NSF).
