Major research projects which have been completed in the CAMAS facility:

Researchers discussing experiment
  • (2014) Dr. Sunday Eiselt, Southern Methodist University. LA-ICP-MS provenancing micaceous schists in Sedentary Period (A.D. 1000-1070) Hohokam ceramics, Gila River Indian Community.
  • (2014) Dr. Richard Holdaway, Paleocol Research, NZ. LA-ICP-MS trace element profiling of subfossil moa (Aves: Dinornithiformes) bone to determine whether evidence of migratory behavior could be discerned in samples recovered from deposits immediately preceding human colonization.
  • (2014) Ph.D. candidate Kristen Carlson, University of Oklahoma. LA-ICP-MS analysis of early Holocene bison enamel to infer possible migratory pathways and source populations at midwestern kill sites.
  • (2014) M.S. candidate Matt DeCarlo, Cal State Bakersfield. Optical and SEM-based imaging of surface dental resin peels for identification and quantification of butchering marks from taphonomic alteration, Owl Cave (Wasden Site) mammoth specimens.
  • (2013) M.S. candidate Meaghan Jones, Boston University. SEM-EDS and LA-ICP-MS analysis to investigate trace element incorporation in dental enamel to forensically 鈥榮ource鈥� historical undocumented skeletal material from Columbia, in order to determine whether biogeochemical elemental signatures could assign individuals to regions of residence.
  • (2013) Ph.D. student Amy Commendador, Idaho Museum of Natural History. Isotope ratio mass spectrometry (IRMS). Using archaeofaunal stable isotopes to create a dietary food web of the island, she demonstrated that terrestrial animal sources (tentatively identified as the Polynesian Rat, Rattus exulans) make up over 80% of the total dietary protein of the prehistoric Easter Islanders.
  • (2012) Ph.D. candidate Alex Morrison, University of Hawaii. LA-ICP-MS to document sub-source variation in obsidian deposits on Easter Island, and correlated this source variation with the distribution of surface artifacts across the island.
  • (2012 & 2014) Doctoral candidate Monica Tromp, University of Auckland, NZ. Developed optimized SEM-EDS auto-identification routines for quantifying large numbers of dental calculus-embedded phytoliths in eastern (Rapa Nui) and western (Vanuatu) Pacific archaeological sites.
