Cody Ross

Cody Ross is a Researcher at the Max Planck Institute for Evolutionary Anthropology's Department of Human Behavior, Ecology and Culture. His research applies quantitative models to human behavior, focusing on ecological and cultural interactions. He is developing a longitudinal field site in Colombia to study social networks, wealth inequality, and ecological change.

His work integrates pure and applied research, emphasizing mathematical approaches to cooperation, reciprocity, and inequality. Recent publications analyze social networks in rural Colombia, cross-cultural fertility patterns, and parochial altruism. Methodologically, he develops R packages like STRAND and IPDToolkit for Bayesian analysis of network data and game-theoretic simulations.

Collaborative projects span global populations including BaYaka foragers (Congo Basin), Tsimane horticulturalists (Bolivia), and rural Colombian communities. Key findings challenge assumptions about nonmonogamous family structures and reveal how women's subsistence networks facilitate cultural transmission.

Research has been published in PNAS, Science Advances, and Evolutionary Human Sciences, demonstrating expertise in statistical modeling of social dynamics across diverse societies.
