As an anthropologist, I am interested in how market integration influences human movement and infectious disease ecology. My dissertation work focuses on these relationships in rural northeast Madagascar, where smallholder farmers are increasingly shifting from subsistence crops to cash crops, particularly vanilla. This change has wide-ranging effects on the health of farmers and their families, and I use tools from network science, epidemiology, and human biology to better understand these effects with an aim to inform interventions. In doing so, I draw on One Health as an organizing framework that emphasizes the interconnections of human, animal, and environmental health.
