Dr. Teichroeb is a primate behavioural ecologist who 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 concensus 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.
