About  

I study human diet as a link between biology, culture and environment, focusing on stable isotope analysis of archaeological human skeletal remains. My bioarchaeological work is informed by ties to human biology and primatology. I chiefly work with European skeletal samples, and also use stable isotope analysis to study diet and stress among modern humans and non-human primates.

My research examines how humans come to embody biological and social aspects of their environments. I do this using a life history perspective, focusing both on proximate (e.g., developmental) and ultimate (e.g., sociopolitical) influences on human biology and behavior. Whereas proximately, adult health and disease is affected by the environment, individual aspects of physiology, and early-life growing conditions, ultimately, these stressors are tied to social and political factors such as structural violence, demographic transition, etc. My research incorporates human skeletal populations as well as extant non-human primates to tease apart the synergistic relationship between environmental impacts at multiple scales.

The Bioarchaeology and Biochemistry Laboratory is equipped to facilitate a wide variety of sample preparation for isotopic analyses, ranging from mineralized tissues, to soft tissues, to plant tissues. Some current projects are described below. 

 

Research projects 

My main research project is the Bioarchaeology of Mediterranean Colonies Project (BMCP) which I co-direct with funding from a NSF Research Experience for Undergraduates (REU) grant (website: https://research.franklin.uga.edu/reu/ ; student blog: https://anthroreublog.wordpress.com/about-2/ ). We examine biocultural consequences of colonization in the 8-5th c. BCE Greek Mediterranean, using interdisciplinary methods that characterize migration, health, and lifestyle changes. The scope of my research in colonization and culture contact extends to a second project on the Georgia coast, examining 16-17th c. Spanish missionization’s impact on lifestyles and health of Guale indigenous Americans. In both projects, we examine biocultural consequences of culture contact at two scales: across generations at the colonies, and within an individual’s lifespan, by studying weaning, and childhood and adult health, diet, and disease incidence.

A third project I co-direct examines early life impacts on later life health outcomes in wild gelada monkeys. Collaboratively, we are exploring the roles and interactions between early weaning – speculatively stimulated by male takeovers in this social, infanticidal primate – and development of the gut microbiome in affecting later life health, using a longitudinal approach. The microbiome mediates health, behavior, and social-ecological landscapes in ways that require living subjects to understand but can be extrapolated to past human health and disease.

In addition to these projects, I continue to conduct collaborative research into childhood diet and adult health in my field sites in North-Central Poland, and in mainland Italy.
