Research
  • My research revolves around the evolution of sociality and social behavior in nonhuman primates with digressions into life history theory, reproductive seasonality, taxonomy, and research methods. 
  • I have worked on captive South American callitrichid monkeys (primarily common marmosets, Callithrix jacchus) in order to test hypotheses on predator-prey interactions (e.g., use of sentinels, effects of group size on vigilance), reproductive strategies (cause and consequences of deviations from monogamy), and cooperative infant care (effects of number of helpers). 
  • In addition, I studied wild Nepalese Gray langurs (Semnopithecus schistaceus) focusing particularly on costs of group size and ecological effects on female social relationships. 
  • In the last years, I studied wild Phayre's leaf monkeys (Trachypithecus phayrei crepusculus) focusing on the costs and benefits of sociality, the ecology of female relationships, and male reproductive strategies. 
  • In addition, I extended my work on comparative research with an emphasis on phylogenetic constraints on behavior, socio-ecological models, and primate life histories.
