Julie Teichroeb
Associate Professor


Julie Teichroeb received her Ph.D. in primatology from the University of Calgary in 2009 before taking post-doc positions at McGill University, the University of California Santa Cruz, and Duke University. Julie primarily examines the evolution of sociality, focusing on the determinants of social organization and the costs and benefits of group-living. She is particularly interested in the relative influence of social and ecological pressures on group dynamics in primates. Her current fieldwork is being carried out at Lake Nabugabo, Uganda and is focused on two species, vervet monkeys (Chlorocebus pygerythrus) and Angolan colobus (Colobus angolensis ruwenzorii). Topics of current interest for the vervets include understanding consensus costs in group movements and decision-making during social foraging, utilizing field experiments to ask particular questions. For the colobus, work is underway to determine their patterns of sociality within a dynamic fission-fusion system.
