I am interested in using novel and integrative methods to test the Hygiene Hypothesis and Disappearing Microbiota Hypothesis, which posit that decreased exposure in parasites and bacterial diversity, respectively, have resulted in the increase in allergic and autoimmune disorders that we are seeing in economically developed nations. Specifically, my research explores how social and economic change alters parasite exposure and bacterial diversity and how this change contributes to immune dysregulation among the Shuar of Amazonian Ecuador. I am interested in combining technologies from microbiology, genetics, and anthropology in order to understand the role that bacterial and helminth exposure plays in normal human immune function.
Other research interests include Evolutionary Medicine, disgust psychology as a mechanism for pathogen avoidance, circumpolar adaptation and health, processes and mechanisms related to the development of atopic disorders, endocrine and cardiovascular health, immunology, psychosocial stress, skeletal biology and physical activity.
