Mari is a PhD student in the Program in Applied and Computational Mathematics. She is broadly interested in using mathematical and computational models to study collective behavior in human and animal groups, particularly as they relate to inter-individual differences and social structures. Prior to coming to Princeton, Mari graduated from Yale University with a Bachelor of Science in Physics and Sociology. While there, she conducted research on a variety of topics, ranging from supermassive black holes and galaxy clusters to gunshot victimization networks and human cooperation. Her Sociology senior thesis used evolutionary game theory to model the role of heuristics in fairness-oriented behavior.
