Sebastián is interested in cultural evolution and evolutionary social dynamics in human and animal groups. Through formal models, he studies the emergence of group-level behaviors when social and cultural traits shape the individual's interactions. His work combines questions and theory from social sciences and biology and uses mathematical and computational tools to answer them. Before coming to Princeton, Sebastián graduated from the Universidad Nacional Autónoma de México (UNAM) with a Bachelor in Technology and from the Universidad Autónoma de Querétaro (UAQ) with a Bachelor in Anthropology. He worked on topics ranging from complex microbial networks to the mechanisms of knowledge transmission and technology transfer.
