I conduct archaeological research on prehispanic communities in the north-central highlands of Peru. Specifically, my work examines ceramic production and consumption from a situated learning approach to understand how local villages mediated shifts in political economy. One way I do this is through the study of the technological attributes of pottery, including the paste recipes of specific vessel types. In doing so, I evaluate the creation, maintenance, and negotiation of local craft traditions and identify potting communities of practice. My work links theories of practice and technology to gain a diachronic understanding of ceramic production and social learning at the village level, and scales up to the regional context to elucidate social boundaries and economic relationships. As a Research Assistant at the Field Museum's Elemental Analysis Facility since 2016, I have received training in several archaeometric techniques. This includes laser ablation - inductively coupled plasma - mass spectrometry (LA-ICP-MS) and petrographic thin-section analysis, which I employ in my dissertation to examine variability in ceramic technologies over time and between discrete archaeological sites.
I have nine years of excavation and lab experience at both highland and coastal archaeological sites in Peru. I also participated in historic archaeology projects in Chicago, US and the Bahamas.
Since 2016, I have studied pottery from museum collections at the Museo Arqueológico de Ancash (Ancash Archaeology Museum ) in Peru, the American Museum of Natural History, and the Field Museum. I also served as the Textiles and Perishables Specialist for PIARA (piaraperu.org) at the site of Hualcayán in Ancash, Peru from 2011-2014. As a part of this position, I cleaned, catalogued, and analyzed perishable materials recovered from mortuary contexts. This work formed the basis of my master's thesis at Purdue University.

Research Currently in Progress
Currently, I co-direct the Proyecto de Investigación Arqueológico - Jecosh (Jecosh Archaeological Research Project or PIAJ) in highland Ancash, Peru with colleagues Emily A. Sharp and Denisse Herrera Rondan. For this project our goal is to examine shifts in village life at the site of Jecosh between the Early Intermediate Period (ca. 100-700 CE) and the Middle Horizon (ca. 700-1000 CE) through excavations of domestic and mortuary contexts. We completed excavation in 2017, which revealed previously unknown mortuary practices and household architecture, as well as a unique ceramic assemblage. Our analysis of these findings is currently ongoing. My research on this collaborative project is supported by the National Science Foundation, the Wenner-Gren Foundation, the Rust Family Foundation, and the University of Illinois at Chicago Office of the Chancellor.
I am also undertaking a comparative petrographic thin-section analysis of prehispanic pottery from six discrete archaeological sites in the Callejón de Huaylas in collaboration with Dr. Isabelle Druc.
