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).

I hope to integrate morphological, genetic, and behavioral data to better understand how variation in canine tooth size is produced and maintained.

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. I address my research questions through a combination of behavioral observations of primates in the field with endocrinology, genetics, and digital measurements of morphology. For my PhD dissertation, I am studying the reproductive ecology of Kinda baboons at the Kasanka Baboon Project in Zambia.Education

For my masters project I studied the relationship between sociality and fitness in the rhesus macaque through non-invasive markers of immune activation and HPA axis function. This research aimed 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 am studying both pre- and post-copulatory mechanisms by which 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.

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.

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.Education

Research Interests
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.
