Jayde Hirniak is a PhD student in the School of Human Evolution and Social Change at Arizona State University. Her research interests include modern human origins, timing and impact of volcanic eruptions, archaeological site formation processes, and advancing field survey methods. She has worked on various archaeological projects in Italy, South Africa, Greece and Kenya. Her current work focuses on using cryptotephra, microscopic glass shards from a volcanic eruption, to better date and correlate archaeological sites in northern Italy and South Africa.
Rachel Lee Johnson is an 4th year archaeology PhD student at Tulane University and a 2016 recipient of the National Science Foundation Graduate Research Fellowship (NSF-GRFP). Prior to coming to Tulane, Johnson earned a B.A. in anthropology and a B.S. in geology from the University of Pittsburgh (2016). Her dissertation research seeks to evaluate the economic and social relationships between the Andean highlands and the Upper Amazon during the Initial Period (1700-800 BCE) and Early Horizon (800-300 BCE) through the reconstruction of trade networks via material sourcing and the application of archaeometric techniques, like ceramic petrography, portable x-ray fluorescence (pXRF), and instrumental neutron activation analysis (INAA). At a broader level, she is interested in questions surrounding the development of social complexity and in the social and economic processes relating to craft production, trade, and material consumption.
Emily J. Kate is Ph.D. candidate in The Pennsylvania State University Department of Anthropology. Her dissertation investigates the impact of migration on the socio-political landscape of the Central Highlands of Mesoamerica during the Epiclassic period (~AD 550-900). Broadly, she specializes in bioarchaeology, isotopic reconstructions of paleodiet and ancient migration patterns, paleodemography, and radiometric chronology building.
