Zoologist Dr Charlotte Uhlenbroek, with her passion for primates, has been hailed as the new wildlife guru. Uhlenbroek was born in London but spent only 10 days on British soil before her parents moved to Ghana. After more globetrotting, Uhlenbroek's family moved to Nepal and often went trekking in the Himalayas.
Uhlenbroek first made her UK TV debut on Dawn To Dusk, in the late 1990s, a BBC series presented by Jonathan Scott, about chimps in the Gombe National Park in Tanzania.
Other BBC programmes she has subsequently presented include Chimpanzee Diary, Cousins (2000), Congo's Secret Chimps (2001), Talking with Animals (2002), Jungle (2003) and Secret Gorillas Of Mondika (2005).
