     I study consistent individual differences in behavior or ‘personality’ in primates within an evolutionary and life-history framework.

     

    I am especially interested in the ecological correlates and fitness consequences of variation in behavioral traits such as boldness and sociability within primate populations. I investigate these issues through systematic empirical study in wild vervet monkeys at Soetdoring Nature Reserve in South Africa. Some of my primary research questions are:

    • Do personality traits such as boldness influence individuals’ behavior in situations with risk-reward trade-offs, such as foraging under predation risk?
    • Are individual differences in social foraging strategies and within-group spatial position associated with differences in personality traits such as boldness and sociability?
    • How are each of these variables related to agesex and reproductive state, and how can this variation be interpreted within a life history framework? 

    Together with collaborators, I am expanding this project to include investigation of the proximate factors influencing the personality variation in wild vervet monkeys. I am currently working on a variety of questions regarding the integrative biology of phenotypic (including behavioral) variation within and between populations of wild vervet monkeys at several sites in South Africa with Dr. Christopher Schmitt in the Department of Anthropology at Boston University.

     

    My planned future research includes investigation of the genetic, epigenetic and endocrinological correlates of personality and other phenotypes in vervet monkeys, as well as a longitudinal assessment of the developmental and fitness consequences of personality differences over the lifespan.

     

    ABOUT ME:

     

    I am an integrative biological anthropologist with broad training across the biomedical and evolutionary sciences.

     

    I earned a MBChB degree (South Africa’s version of the U.S.'s MD) from the University of Cape Town, South Africa. While in medical school, I became interested in human and primate evolution, and additionally studied towards a BSc (Med) with a major in Anatomy. This work led to me to publish on gait parameters in Homo floresiensis together with Kit Vaughan. I relocated to the U.S. to begin postgraduate training in Biological Anthropology at New York University in 2007, and completed a MA in primate evolutionary genetics at NYU's Molecular Anthropology Laboratory. For my dissertation, I switched focus to the evolutionary ecology of individual differences in personality within primate populations.

     

    I was born in Poland, raised primarily in South Africa, and am also a naturalized U.S. citizen. I am currently a postdoctoral researcher at the University of Texas at Austin working in the lab of Anthony Di Fiore in the Department of Anthropology.
