Summary

I am an evolutionary social scientist interested in how humans respond adaptively to culturally structured social worlds.

Two main foci of my research are:

1. How do people think about ethnic boundaries? I use cross-cultural and developmental research to examine whether humans cognition is shaped by a history of ethno-linguistic landscapes and how the entailments of these boundaries vary. My primary geographic focus has been among agro-pastoralists in the Peruvian Altiplano along the Quechua-Aymara linguistic border

2. How do our social networks influence reproduction? I examine why and how family members and religiosity affect fertility outcomes across space and time. I also work on why social learning processes influence reproductive decision-making so much and how this can give rise to puzzling phenomena such as the demographic transition, below replacement fertility, and cross-site variation in life history decisions.

I am also starting projects on the origins of ritual participation at a new pilgrimage site, and inter-site variation in collective action on vicuña hunts, both in the Peruvian Altiplano.
