Current Graduate Students

Margaret conducting field research in Honduras.


Margaret Buehler joined our Ph.D. program in August 2017. She completed her master’s degree at Northern Illinois University, with her thesis “Inter-sexual social interaction in wild white-faced capuchins (Cebus capucinus) in Costa Rica. Her dissertation examines the role of subordinate males in social groups of white-faced capuchins in Santa Rosa.




Nelle Kulick, Michaela Brown, Margaret Buehler, and Sophie Lieber in Santa Rosa in 2019


Danielle Kulick, Class of 2020, Double major in Anthropology and Ecology and Evolutionary Biology. Nelle is currently in Santa Rosa collecting data on her project examining male chemo-signaling behaviors in capuchins. These data will form the basis of her Ph.D. in anthropology – co-directed by me (K. Jack) and Dr. Amanda Melin at the University of Calgary. We are so excited to have her on our team!

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 the 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 ongoing 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.
