I am doing my doctoral studies in physical anthropology, primarily in behavioral ecology and evolution. My Ph.D. topic involves issues of spatial representation, coordinated group movement, and vocal communication in primates. I am currently working with woolly monkeys (Lagothrix poeppigii) at the Tiputini Biodiversity Station (TBS), in the Ecuadorian Amazon.

Group travel coordination and vocal communication
A great deal of my research interests concerns the evolution of sociality, and how resource abundance and distribution as well as other factors of the environment affect primate social interactions. In particular, I am interested in how animals make travel decisions in their environment, taking into consideration what animals might know about their environment, what other conspecifics are doing and how animals share a communication system that allows them to coordinate travel movement through their sensory systems. I am currently working on woolly monkeys (Lagothrix), which represent a good model taxon in which to investigate issues of group travel coordination and vocal communication, as they are characterized by a very mobile and fluid travel pattern and also are highly vocal in the wild. For my dissertation research I'm planing to look at what woolly monkeys know about their environment, what sorts of information are conveyed in their vocalizations regarding individual identity and surrounding context of calls, as well as how they might use this information to generate social preference, kin biased behavior, and how animals regulate cooperation and competition between and within groups. I am also developing agent based simulation models to establish the behavioral rules that animals might follow given different possible environmental and social scenarios in silico.
