    Research Interests
    I am interested in how sexual selection has shaped primate cognitive evolution. Sex differences in behavior and cognitive abilities have been demonstrated in humans and non-human primates, but the specific neurobiological underpinnings of such differences remain unknown.

    Research Interests

    My research to date has focused on sexual selection in anthropoid primates, using rhesus macaques (Macaca mulatta) as a model. As a post-doc in James Higham’s lab at New York University, I investigated the causes and consequences of inter-individual variation in red skin ornamentation in this species. I recently joined Tim Clutton-Brock’s research group at the University of Cambridge where I study reproductive strategies in wild meerkats (Suricata suricatta).

    Research Interests
    My research is generally centered in sexual selection and communication. I am interested in understanding variation in sexually selected traits in primates and the evolution of mating system diversity. My research combines observations of wild primates in the field and examining morphology, genetics, and endocrine processes. For my dissertation, I am studying the reproductive ecology of Kinda baboons at the Kasanka Baboon Project in Zambia.

    Research Interests

    For my masters project I am studying the relationship between sociality and fitness in the rhesus macaque through non-invasive markers of immune activation and HPA axis function. This research aims to uncover the role of the immune and endocrine system in mediating the negative health consequences associated with low social integration. For my dissertation, I plan to study both pre- and post-copulatory mechanisms by which promiscuous female primates bias paternity. Specifically, I am interested in mechanisms of cryptic female choice and exploring how sexual selection has acted on female physiology in order to better understand the co-evolution of reproductive strategies in male and female primates.

    I received my undergraduate degree at Skidmore College where I did my thesis studying the cannabinoid system and female sexual behavior in rats. I went to the University of California, Davis where I got my doctorate studying the neurobiology of monogamy. My research focused on the opioid system and its role in adult attachment in the monogamous titi monkey (Callicebus cupreus). My future research goal is to study the relationship between immune functioning and social behavior in male rhesus macaques.

    Research Interests

    For my dissertation I am studying the form and function of guenon face patterns. Guenons are a group of forest monkeys in Africa that exhibit an extraordinary variety of colorful facial displays. Guenons often form polyspecfic groups in which up to six species live side by side, however hybridization between species, while possible, is rare in undisturbed circumstances. This indicates that there are likely pre-mating barriers to heterospecific mating; previous research in my lab has indicated that the face patterns exhibited by guenons are likely contributing to maintaining species boundaries and have been under selective pressures to diversify (i.e. there is evidence of character displacement in sympatric species groups). I will extend this research using a variety of techniques, including computational recognition algorithms based on photographs of guenon faces, modeling of evolutionary scenarios, experiments to assess guenon preferences, and measurements of guenon behavior and ecology.

    I have recently moved to the University of Hull to work with Isabella Capellini on a NERC funded project that aims to understand how the life histories of vertebrates influence the success of species invasions at the different stages of introduction, establishment and spread.

     

    Prior to this I was a a post-doc in James Higham’s lab at New York University investigating how the colourful face patterns of guenon primates were involved in the adaptive radiation of the tribe.

     

    My PhD was supervised by Innes Cuthill and Nick Scott-Samuel at the University of Bristol. I conducted investigations of the beautiful patterning worn by many species of cat and snake, the countershaded coats of ruminants and the camouflage of moths.

    Research Interests


    My research interests are centered on primate development, particularly infancy and adolescence. I am interested in the physiological and behavioral aspects of development and how things like maternal care, social/environmental factors, and stressors influence an individual’s life history trajectory. I am particularly interested in the mechanisms that have evolved to allow young primates to cope with “stressful” events such as weaning and aggression. I completed my MA thesis on the association between early life adversity and developing stress physiology in free-ranging juvenile rhesus macaques on Cayo Santiago. I recently joined the Interdepartmental Doctoral Program in Anthropological Sciences at Stony Brook University as a Ph.D student.

    In the Fall of 2015, I started a dual Ph. D in Integrative Biology, and Ecology, Evolutionary Biology, and Behavior (EEBB) at Michigan State University. I joined Dr. Kay Holekamp’s lab, which focuses on the ontogenetic development, physiological substrates, and evolution of mammalian behavior, using the free-living spotted hyena as a model species. My specific project has not yet been formalized, but I am interested in studying the energetics of maternal investment, factors influencing female mate choice, or individual variation in stress physiology, and coupling field observations with genetic/endocrinological/microbial analyses.
