Andrew Zipkin is an analytical chemist and archaeological scientist with over a decade of experience in elemental characterization, strontium isotope geochemistry, compositional data analysis, provenience studies, geographic information science, and anthropological and environmental archaeology. He currently works as a mass spectrometrist and atomic spectroscopist for a materials science-focused contract research organization. Zipkin has also been affiliated with ASU in multiple capacities since 2018. Previously, he was a National Science Foundation SBE Postdoctoral Fellow at the University of Illinois at Urbana-Champaign and a Ph.D. student at The George Washington University. He conducted archaeological, ethnographic, and geological field work in Alaska, Kenya, Malawi, Namibia, South Africa, and Zambia between 2007 and 2019. In academic research, Andrew primarily focuses on developing minimally destructive methods for geochemical provenience studies and other classification-oriented problems in archaeology. Secondary research areas include material properties of hafting adhesives, identification of heat treated toolstone, and detecting chemical diagenesis in faunal hard tissue. His main archaeomaterials of interest are ochre, silcrete, and ostrich eggshell. He was the SAS Vice President for Social Media and Outreach from 2017-2020.

Adrian Burke is an archaeologist specializing in the physico-chemical characterization of rocks and minerals used in the past to make tools and ornaments. He carries out most of his research, including geoarchaeological fieldwork, in northeastern North America. He currently directs an XRF laboratory dedicated to the geochemical analysis of geological samples and archaeological artifacts. He also uses other techniques such as thin section petrography, SEM, XRD, and NAA to characterize raw materials.
Rebekah Kurpiel is the Director of La Trobe Archaeology Research Partnerships at La Trobe University in Melbourne, Australia. In terms of archaeological science, she is interested in understanding past trade and transport patterns and in developing methods and methodologies for sourcing stone and ochre artefacts to investigate this. Rebekah has experience in undertaking trace element analysis (ICP-MS and pXRF), mineralogical analysis (XRD) and Pb isotope geochemistry to determine where artefacts originated. Rebekah is also interested in how scientific techniques can be employed to produce better outcomes in the context of cultural heritage/resource management. Rebekah has active research projects in Australia and South Africa, including work funded by the Australian Research Council, and is a committee member of the Australasian Research Cluster for Archaeological Science.
