About me

I am an anthropological archaeologist of coastal South America. My research centers human adaptations to life at the intersection of two challenging environments: the Pacific Ocean and the deserts of the Peruvian coast. This work examines the intersection between subsistence strategies, economic systems, and environmental variability.

The aridity of the Peruvian coast allows for outstanding preservation of materials which are normally not observed in archaeological contexts, such as plant remains and basketry. To address these rich datasets, I draw on a diverse set of interdisciplinary approaches, especially ethnohistory, zooarchaeology, and spatial approaches (GIS, drone mapping). I am also interested in Bayesian approaches to archaeological problems.

I received my BA in Anthropology from Harvard College (2012), and my MA (2015) and PhD (2022) from the University of Michigan. Currently, I am a Postdoctoral Research Associate in Zooarchaeology for the ERC-LASTJOURNEY project at the University of Exeter.
