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 from the perspective of constraints on individuals and their subsequent decision-making. The relative influence of social and ecological pressures on social organization is of particular interest. Most of her current fieldwork is being carried out at Lake Nabugabo, Uganda and is focused on two primate species, vervet monkeys (Chlorocebus pygerythrus) and Angolan colobus (Colobus angolensis ruwenzorii). Topics currently under investigation for the vervets include understanding consensus costs in group movements and decision-making during social foraging, often utilizing field experiments. The colobus form a unique multilevel society within the primates and work is underway to determine how their dynamic patterns of sociality evolved.
