Bio

I am an environmental archaeologist with primary research interests concerning the fire-climate-society nexus. My regional expertise is in the Southwestern US, but I maintain active research interests in the Northern Plains as well as Oceania. My research projects are necessarily interdisciplinary, often including dendrochronology, archaeology, ethnography, and sedimentary paleoecology.

I maintain theoretical interests in ecosystems ecology, particularly in the study of human impacts on social-ecological resilience and vulnerability. Sustainability issues, as framed by resilience theory, inform the questions that drive my research projects. How do human activities alter the response of ecosystems to climate change? What lessons can we learn for contemporary ecosystem management or restoration?

I maintain additional research interests in archaeological method and theory, particularly the role of geoarchaeology in building and testing inferences about village societies. To this end, I use stratigraphy, micromorphology, and soil/sediment chemistry to reconstruct the life histories of ancient dwellings, ritual structures, and community spaces.

Research

Jemez Fire & Humans in Resilient Ecosystems Project (Jemez FHiRE Project)

This interdisciplinary project is a collaboration between scientists from SMU, Harvard, the University of Arizona, Simon Fraser University, and the USDA Fire Sciences Laboratory. We are partnering with the Pueblo of Jemez to investigate the long-term dynamics of human societies, forests, climate, and fire regimes in Southwestern ponderosa pine forests. Using ethnography, archaeology, paleoecology, dendrochronology, and dynamic ecological simulations, this project builds on the methodology I developed during my dissertation research. Other tribal partners from the Pueblo of Zuni and the White Mountain Apache and Hopi Tribes are working with us on the oral traditions, knowledge, and practice associated with living in ponderosa pine forests for multiple centuries. Our goal is to test hypotheses about human impacts on the resilience and vulnerability of pine forests and fire regimes as human population density increased in ancient agricultural communities. The Ancestral Jemez landscape was densely populated enough to  qualify as a "wildland-urban interface" for centuries; this is a land-use category with which contemporary policymakers struggle to manage forests and fire risks.

This research is supported by a multi-year research award from the National Science Foundation's Dynamics of Coupled Natural-Human Systems program (GEO-1114898).

Post-Lapita Fiji Project

I am also collaborating with archaeologists from Ohio State University and Idaho State University to test ecological hypotheses about the economic and political transformations in Fiji at the end of the Lapita period roughly 2,500 years ago. At that time, Ancestral Fijians developed extensive inland agricultural systems. Our goal is to determine how these communities made decisions about economic trade-offs, movement of settlements, and the investment in agriculture in the context of environmental degradation, population growth, and intercommunity conflict.

This research is supported by a multi-year research award from the National Science Foundation's  Archaeology program (BCS-1216312).
