Sarah Mathew - class of 2003

Sarah is currently a graduate student in Biological Anthropology at UCLA studying the evolution of cooperation. She uses mathematical modeling to understand how cooperative strategies can evolve and persist in populations, mostly through an evolutionary game theoretic framework. She is also pursuing empirical work on the evolved psychological mechanisms and cultural norms that motivate people to participate in warfare, specifically focusing on why people cooperate and behave altruistically in warfare, by studying cattle-raiding among pastoralist societies in East Africa. Her senior thesis research in the Altmann lab focused on intergroup relations and between-group dominance hierarchies in Amboseli baboons.

Nga Nguyen - former graduate student, Ph.D. 2006
nganguyen@fullerton.edu

Walter Odede - former graduate student

Walter has a background in environmental science. He is interested in spatial ecology, geostatistics, and conservation biology. His MSc research focused on the effects of land-cover dynamics on foraging ecology of Amboseli yellow baboons. He analyzed landscape changes in Amboseli between 1984 and 2001 using GIS techniques and related these changes to baboon behavior and habitat use using data from the Amboseli Baboon Project's database, BABASE. He intends to continue with academic and professional development in environmental science specializing in landscape ecology. Walter received his GIS training from International Livestock Research Institute (ILRI).

Laura Okpala - class of 2006

Laura spent her four years at Princeton working in the Altmann lab performing fecal prep, assays and data entry. Her senior thesis focused on examining gender differences that arise in orphaned yellow baboons, specifically in terms of fecal glucocorticoid levels, survival, wounding Incidence, and healing time. These research interests led her to spend time in Amboseli National Park in Kenya. Laura is currentlly involved in investor relations and strategic consulting at a small firm, working with numerous life science and biotechnology companies around the world. She hopes in the future to have some of her prior research published. 

Daphne Onderdonk - database manager

Daphne played a critical role in updating and maintaining the large behavioral, ecological, and demographic database on the Amboseli Baboon Project. Every month, all the field data was mailed to Princeton. Daphne would then integrate the data into the larger database and pull out information needed for analyses by Susan Alberts, Jeanne Altmann and our collaborators and students. Daphne has a Bachelor's degree in Biological Anthropology from Harvard University and a Master's degree in Zoology from the University of Florida. She has conducted field work in several African countries.

Ethan Pride - former graduate student, Ph.D. 2003

Ethan finished his doctorate on group size, behavior, cortisol, and demography of ring-tailed lemurs (Lemur catta). In the Altmann lab, he measured cortisol concentrations in fecal samples that he collected from wild lemurs in Madagascar, and used these to show patterns of stress within his study population. He is currently an Assistant Professor in the Department of Biology at the College of New Jersey.

Rose's senior thesis project consisted of testing the hypothesis that monogamous P. polionotus which have a history of reproductive failure with their current partner will be more likely to switch mates when given the opportunity than pairs with a history of reproductive success. To test this hypothesis, she ran mutual mate choice tests, with two pairs of opposite sex at a time.

Suzanne Rossi - class of 2008

Suzanne currently works as a full-time clinical research assistant at Pennsylvania Oncology/Hematology Associates, a private oncology practice affiliated with Pennsylvania Hospital.  She also volunteers once a week at Covenant House, a community crisis center for teens and young adults, and is in the process of applying to medical school.  

Nancy Rubenstein - research assistant

As a research assistant in Jeanne Altmann's lab, Nancy helped prepare fecal samples for radioimmunoassay. In addition, she helped train students new to the lab, and she also entered and proofread data. She is currently a pre-school teacher in Pennington, New Jersey.

Lili Shek - class of 2004

Lili's senior thesis examined the effects of termperature and rainfall on the reproduction of yellow baboons in Amboseli.  For this research, she extracted hormones such as corticosterone, testosterone, and estrogen from female and male baboon fecal samples.  After graduating in 2004, Lili worked as a Project 55 fellow in HIV-1 research.  Currently, she is in the medical class of 2010 at the University of Rochester School of Medicine and Dentistry.

Franklin West - undergraduate, Morehouse College

In a previous summer, Franklin examined the effects of wet/dry season, drought, and hierarchy on stress levels in male yellow baboons, Papio cynocephalus. He assessed stress levels by examining glucocorticoid levels in fecal samples from test subjects. Glucocorticoids are a suite of stress related steroid hormones. He compared the glucocorticoid levels to rain fall levels and ranks of individuals over a time period of two years. This is currently an ongoing project.

With Professor Altmann as her thesis advisor, Jennifer worked to determine socio-ecological, behavioral and hormonal effects on the timing of menarche in female baboons. She mainly worked in the lab, preparing samples and running radioimmunoassays for different hormones. She is currently enrolled at Robert Wood Johnson Medical School in New Brunswick, New Jersey.

Pooja Kulkarni - high school intern, Plainsboro High School

Pooja is currently a senior in high school and is interning in the Altmann Lab. She is involved with preparing fecal samples, helping to enter data in the lab, and learning the various stages of research that occur there.

Carolina Simao - Rice University, class of 2009

Carolina is currently an undergraduate student studying Ecology and Evolutionary Biology at Rice University. Her summer project investigated postpartum amenorrhea in female baboons, specifically looking at hormone levels during this time period and their relation to factors such as rank, age or parity. She has also been involved with the various stages of preparing fecal samples, running radioimmunoassays, and entering data in the Altmann Lab. In the future she hopes to pursue a graduate degree in tropical entomology.

Allison Williams - class of 2009

Allison’s thesis involves white monkey syndrome, a rare disease that affects some infants of the yellow baboons, Papio cynocephalus, in Amboseli. They present with many symptoms including white fur, loss of hair, anemia, limping and, in some cases, death. Allison worked in the Altmann lab over the summer preparing fecal samples and running radioimmunoassays for the stress hormone corticosterone. She plans on examining stress levels of the mothers of sick infants, analyzing water samples of Amboseli for metal toxicity and will explore other environmental influences that may trigger the occurrence of white monkey syndrome in the infants.

Mio Yanagisawa - class of 2009

Mio's senior thesis project looks into the behavioral and hormonal responses as well as coping mechanisms of female baboons to the loss of a close companion. She will question whether the baboons who have survived a loss experienced any changes in their social network and/or compensated for that loss by adjusting their grooming interactions. Furthermore, she will explore any fluctuations in glucocorticoid levels of the bereaved after the death of a friend.
