Elizabeth in the Field I am currently a Ph.D. student working with Dr. Anne Pusey. For my dissertation research, I am studying the development, acquisition, and transmission of tool-use skills in infant to ten-year-old wild chimpanzees. Each fall for the past three years, I spent 3 months following wild chimpanzees in Gombe National Park to collect the data for this project. My interest in infant development and tool-use skills reflects many of the past research projects I have been involved in. While an undergraduate at Duke University, I spent several semesters studying mother-infant interactions and foraging techniques in a weird and wonderful primate, the Aye-aye (Daubentonia madagascariensis), at the Duke Primate Center. I also spent one summer as a research intern at the Kewalo Basin Marine Mammal Laboratory in Honolulu studying bottlenose dolphin cognition. After graduation, I completed a research assistantship at the National Zoological Park as part of the Golden Lion Tamarin Reintroduction Project, and then returned to working on dolphin cognition as an intern at the Living Seas, Epcot Center. These diverse interests finally solidified and resulted in my coming to work under Dr. Pusey on the wild chimpanzees of Gombe.

Each year, I spend from October to December at Gombe National Park following mothers and their offspring and videotaping sessions of a particular tool-use skill known as termite-fishing. Termite-fishing involves selecting a piece of vegetation, modifying it into a long, flexible, wand-shaped tool, inserting it into a termite mound, and then extracting the termites that attack and cling to the tool. This tool-use skill is very complex and it may take young chimpanzees many years to learn. The developmental and acquisitional processes these individuals go through are the focus of my dissertation research. I collect video data each day while at Gombe and then bring it back to Minnesota to analyze. While in Minnesota, I also use the long-term data stored at the JGI Center for Primate Studies to supplement the data I've gathered in the field. I have just completed my final field season and I have now gathered over 70 hours of video footage of termite-fishing. Preliminary analyses of this data has suggested that chimpanzees learn much of their skills socially and that young females learn faster than young males. I am currently in the process of watching the video from the final field season and performing analyses on the full, four-year dataset.

Elizabeth received her Ph.D. in 2003 and now works in Chicago at Lincoln Park Zoo as Director of LPZ's Lester E. Fisher Center for the Study and Conservation of Apes and also as a faculty member of the University of Chicago's Committee on Evolutionary Biology. Elizabeth and the zoo are now working closely with Dr. Pusey and the Jane Goodall Institute on collaborative projects involving the Gombe chimpanzees.
