Research interests

I am a primate behavioral ecologist broadly interested in the costs and benefits associated with group living and the role that signaling plays in moderating these costs and facilitating the benefits. My field research is focused primarily on anti-predator communication in wild tufted capuchin monkeys (Cebus apella nigritus) in Iguazú National Park, Argentina, and uses a largely experimental approach.  Specifically, I use decoys of predators, playbacks of alarm calls and predator vocalizations, and controlled provisioning experiments to investigate the production and perception of "honest" and "deceptive" alarm calls, at both ultimate and proximate levels. My current work continues to use field experiments, integrated with hormonal and bioacoustic analysis (with Barbara Tiddi, Michael Heistermann  & Kurt Hammerschmidt of the DPZ), to better understand the proximate mechanisms underpinning "deceptive" alarm calls as well as apparent counter-deception among call receivers. In addition, I am also investigating the mechanisms by which capuchins acquire recognition of heterospecific alarm calls.


Other projects

In collaboration with Barbara Tiddi, Michael Heistermann, and Kurt Hammerschmidt, we are combining field experiments with hormone and bioacoustic analysis to investigate aspects of female sexual signaling and mate choice among wild tufted capuchins.

In collaboration with Andreas Koenig, Carola Borries, and Clara Scarry, we are testing several assumptions and predictions of ecological models of female social relationships.
