About Me

My research is focused on Mesoamerica, where I investigate the complex dynamics between people and their environments throughout the Holocene. I am particularly interested in understanding the emergence of complexity among the earliest Maya agricultural communities, and the fluctuating environmental and climatic contexts in which they appeared. By exploring the local-level human responses to environmental or climatic change, archaeology can highlight the ways that people in the past adapted to the challenges of climatic shifts. I combine stable isotope analyses, radiocarbon dating, and spatial analyses with approaches from environmental archaeology and human ecology to examine these questions. While my current projects are based in western Belize, I am also motivated by the potential of comparative archaeology to develop models of past human-environment interaction to identify how similar evolutionary processes in the Old and New Worlds resulted in divergent, yet similar social and economic forms.

My current research projects include:

  • Agricultural origins and the Archaic-Formative transition (2000-1000 BC) ​through excavation of rockshelters, radiocarbon dating, and isocape modeling in western Belize

  • Relationship between ancient Maya diet and extreme climate events (e.g., drought, hurricanes) using multi-isotopic analyses

  • Origins of urbanism in the Maya lowalnds

  • Meta-analyses of isotopic “big data” from Mesoamerica and the Caribbean

  • Human-dog interaction in the Maya lowlands

  • Upper Belize Valley obsidian geochemical sourcing project

  • Upper Belize Valley lidar (light detection and ranging) analysis
