Gillian King-Bailey is a Ph.D. candidate currently conducting her field research in Santa Rosa National Park, Costa Rica. Her project, entitled “Socioecological correlates of androgens and glucocorticoids in female white-faced capuchins”, examines how androgen and cortisol levels are related to variation and individual behavior and reproductive success in female white-faced capuchins. She has secured funding for this project from the Stone Center for Latin American Studies at Tulane University, the Anthropology graduate student fund at Tulane, The Nacey Maggioncalda Foundation, and the International Primatological Society. She spent the first half of her second year in the program managing the the field site for the Santa Rosa Capuchin project and will be conducting field work from January – Dec 2017. While in residence at Tulane she enjoys mentoring youth through MentorNOLA, Each One Saves One, and leading Girls in STEM at Tulane (GiST) workshops. She is from northern California and graduated from Sonoma State University. 

Current undergraduate lab members:

Nathalie Clarke, Class of 2020 is a freshman from Paris, France,  interested in double majoring in Anthropology and either Psychology or Environmental Biology. She will be helping Professor Jack sort through some of the data for her research on the role that Major Histocompatibility Complex plays on mating and dispersal patterns of the white-faced capuchin population in Santa Rosa National Park.

Stephen Cortese, Class of 2018. Double majoring in neuroscience and evolutionary biology. Stephen received a CELT Summer Student/Faculty Research award in 2016 to assist on our lab project entitled “Primate Health Responses to Extreme Drought in Northwestern Costa Rica”. 





Mikayla Stern-Ellis at Playa Naranjo in Santa Rosa National Park

Mikayla Stern-Ellis Class of 2017. Double major in Biological Anthropology and Ecology and Evolutionary Biology. She began her adventures in field research at Santa Rosa National Park with white faced capuchins in 2014 and 2015 and plans to completed her honors thesis research at the site in 2016, focusing on the impact of climate change on primate activity budgets.

Interested in joining my lab?

Undergraduate students should make an appointment to meet with me. All students must be able to commit to a minimum of 3 hours of work per week. Duties will vary with skill levels and interests, but it is my intent that lab interns will gain skills in data input, management, analysis, and presentation. My goal is to work with each of you to help you gain skills needed to engage in successful research and, eventually, publishing the results in academic journals.

Graduate students who enter our doctoral program under my guidance are expected to conduct field research at my long term study site in Santa Rosa National Park, Costa Rica. While I am primarily interested in having students who would like to collaborate on research on the white-faced capuchin monkeys, I am also open to comparative studies that focus on the other two primate species at the study site. Our capuchin project has been on-going since 1983, and student projects are vital to maintenance of this long term study. If you are interested in applying, please contact me via email and include a brief description of the type of research that you are interested in pursuing.
