mitaniI am a primate behavioral ecologist who investigates the behavior of our closest living relatives, the apes. My current research involves studies of an extremely large community of wild chimpanzees at Ngogo, Kibale National Park, Uganda. During the past 39 years, I have conducted fieldwork on the behavior of all five kinds of apes: gibbons and orangutans in Indonesia, gorillas in Rwanda, bonobos in the Democratic Republic of Congo, and chimpanzees in Uganda and Tanzania. In my work, I address questions about ape social behavior and communication.
