Lab Director:  Katharine Jack

Current Graduate Students

Margaret conducting field research in Honduras.

Margaret Buehler joined our Ph.D program in August 2017. She completed her masters degree at Northern Illinois University, with her thesis “Inter-sexual social interaction in wild white-faced capuchins (Cebus capucinus) in Costa Rica.She is interested in male-female social interaction, particularly relative to reproductive state and hormone concentrations. She would also like to examine social response to environmental degradation and a GIS analysis of long-term home ranging patterns at Santa Rosa.

Lauren Brasington is a Ph.D. candidate who began our program in 2012. She is currently writing her dissertation, which focuses on intersexual conflict, particularly female counterstrategies to infanticide.

Gillian King-Bailey in Colombia 

Gillian King-Bailey joined our PhD program in 2014 and conducted her research in Santa Rosa National Park. She is now writing up her results and completely hormone analyses at the Laboratory for Evolutionary Endocrinology in Primates, with Dr. Stacy Tecot. Gillian’s 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. Gillian’s research is funded by grants from the Nacey Maggioncalda Foundation, International Primatological SocietyStone, Sigma Xi, American Philosophical Society (Lewis and Clark Fund), Tulane’s Center for Latin American Studies, Department of Anthropology, and SLA Dean’s Summer Merit Program. 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 with a B.Sc. in Biology from Sonoma State University. 

Claire Sheller is a Ph.D candidate, currently writing her dissertation while teaching courses at Tulane University. Dissertation title: The emergence of sex-typical behaviors in juvenile white-faced capuchins (Cebus capucinus) in Guanacaste, Costa Rica: Social and biological factors. Her research was funded by the Leakey Foundation as well as Tulane’s Center for Latin American Studies, Department of Anthropology, and SLA Dean’s Summer Merit Program.

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. Independent study credit is possible.

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 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 the 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.
