Main Focus

Andrew Gillreath-Brown is a PhD candidate at Washington State University. He is a computational archaeologist interested in how individuals and groups respond to both large scale processes such as climate change and local processes such as violence and wealth inequality. His PhD research focuses on paleoclimate modeling, which he uses to understand how climate change and other processes stimulated migration, contributed to the precarity of people arriving to new locations, affected crop production, and ultimately resulted in social instability, inequality, and depopulation of portions of the southwestern United States. He also conducts research on tattoo archaeology and ancient music. Currently, he is working on the ArchaeoGLOBE: Island Extinctions Project. The project is focused on examining the impact of human arrivals on island fauna communities at different times and under different modes of production.

Curriculum Vitae

Andrew received his BS in Anthropology and Archaeology from Middle Tennessee State University (TN, USA) in 2011, where he gained a lot of experience in zooarchaeology and completed a Senior Thesis titled “An Exploration of Turtle Shell Rattle Manufacture in the Mississippian Period.” He completed a MS in Applied Geography with a focus in Environmental Archaeology from University of North Texas in 2016. His MS thesis, “Looking Outward from the Village: The Contingencies of Soil Moisture on the Prehistoric Farmed Landscape near Goodman Point Pueblo,” focused on developing a new static geospatial soil moisture model to determine potential prehistoric farming locations and to understand the farmer to agricultural field relationship, and how that relationship may have changed over time. He has done archaeological fieldwork throughout the United States and in Israel. He also attended the Complex Systems Summer School in 2019 at the Santa Fe Institute in New Mexico, USA.
