  • News about Cayo Santiago

    Updates Post-Hurricane Maria

    After a unique macaque colony off the island's coast was hit by Hurricane Maria, its caretakers are rushing to save it—and themselves.

    Autism research suffered a significant setback after an island used for scientific study was ravaged by Hurricane Maria.

  • Research

    Our overall goal is to study genetical, morphological, physiological and behavioral aspects of primate reproductive strategies as shaped by sexual selection. Much of our work has a particular focus on communication and sensory and perceptual ecology, as well as the neuroendocrinological, physiological and immunological processes underlying mechanisms of competition and mate choice. Following Darwin, our research is structured around two related processes: the ways in which individuals compete with members of the same sex both directly and indirectly over reproductive opportunities (intra-sexual selection); and the ways in which individuals attract members of the opposite sex (inter-sexual selection).


    The methods used in our lab are diverse, and include techniques from ethology, biological anthropology, evolutionary biology, computer vision and machine learning, experimental and comparative psychology, endocrinology and immunology, and quantitative and functional genetics.


    A summary of our recent work on adaptive coloration can be found on BBC Earth.

  • Field Sites

    We are active at several field sites. Students may be able to undertake research at these sites, but are welcome to suggest others too.

    Cayo Santiago, Puerto Rico

    Cayo Santiago, Puerto Rico. This island off the coast of Puerto Rico is home to over 1000 rhesus macaques and is administrated by the Caribbean Primate Research Center of the University of Puerto Rico. Our diverse work there includes collaborations with Lauren Brent (Exeter), Noah Snyder-Mackler (UWashington), Dario Maestripieri (UChicago), and Laurie Santos (Yale).

    Tangkoko, Sulawesi, Indonesia

    Tangkoko, Sulawesi, Indonesia. This reserve in northern Sulawesi is home to several habituated groups of crested macaques, a critically endangered species of macaque known for its high levels of social tolerance between group members. The Macaca Nigra Project is hosted by the German Primate Center’s Jr Research Group on Sexual Selection, and is directed by Antje Engelhardt.

    Gashaka, Nigeria

    Gashaka, Nigeria. Gashaka-Gumti is Nigeria’s largest national park, and contains numerous primate species. Around the Kwano and Gashaka field stations are species including chimpanzees, baboons, tantalus monkeys, black and white colobus, putty-nosed guenons and mona monkeys. The site is directed by Volker Sommer (University College London), while the director of baboon research is Caroline Ross (Roehampton University, London).

  • Primate Hormones and Behavior Lab

    We have our own enzyme immuno-assay laboratory, in which we measure primate hormonal and immunological analytes, often measured as metabolites from excreta (feces and urine).

  • PhD Program in Anthropology

    New York University

    The research and training program in our department is distinguished by its unique commitment to integrating laboratory-based and field-based research. We have state-of-the-art laboratories in genetics and molecular systematics, endocrinology, and in paleoanthropology, with superb facilities for both research and teaching in these areas. In addition, faculty and students are conducting primatological and paleoanthropological research at sites in South America, Asia and Africa.
