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.

Nick in the field conducting field work in Costa Rica in 2022

Nick Chapoy started the Anthropology PhD program at Tulane in the fall of 2022. He earned an MRes in primate biology,behavior, and conservation from  Roehampton University (2021) in London and a B.A. in Anthropology and Psychology from the University of Montana (2015). He has spent the last several years as a research assistant working on primate research projects, including chimpanzees and mountain gorillas in Uganda, woolly monkeys in Ecuador, and capuchin monkeys in Costa Rica. Nick’s research interests include how male sociality influences vocal communication in wild capuchin monkeys living in Santa Rosa National Park, Costa Rica.

Celeste with pet snake Reggie!

Celeste Lam is beginning her P.hD. this fall, and we are thrilled to be welcoming her to our lab and to Tulane. Celeste earned a B.Sc. in Psychology (2019) and an MA in Anthropology (2022) from UNC Charlotte. During her undergraduate years, she interned at the Yerkes National Primate Research Center and participated in the Maderas Rainforest Conservancy field school in Costa Rica. Her research interests encompass cross-species conflict, community ecology, and the impact of anthropogenic food on wild primate populations, particularly in relation to behaviors, health, and physiology.

Current undergraduate lab members:

It’s summer time! Congrats to our most recent graduates of Tulane. We are fortunate enough to have two undergraduate students, Hubert Mendez and Evelyn Howard, joining us this summer in Costa Rica to help us collect data on a number of ongoing projects.
