A Cross-Cultural Study of Integration to the Market and Indigenous Health in the Ecuadorian Amazon.

Lifestyle, Stress and risk for the metabolic syndrome in Indigenous Siberians. 

mark siberiaThis project focuses on the impacts of the post-socialist transition on the health and well-being of Siberian reindeer herders.  I collaborating with researchers in Russia to investigate changing household subsistence strategies among Evenki, Eveny and Sakha (Yakut) herders. In this project we are investigating the role of economic status and subsistence activities on psychosocial stress and measures of health and immune function in the circumpolar environment. The goal of the project is to understand the health consequences of rapid social and cultural changes, and to determine the mechanisms through which social and cultural processes affect health and human biology.
