Kahumbu was born on June 25, 1966, and grew up in
Nairobi, Kenya, and there attended primary and secondary school at
Loreto Convent Msongari. She was first mentored by the renowned conservationist
Richard Leakey. She was granted a
Government of Kenya Scholarship to study ecology and biology at
the University of Bristol. She then received her master's degree at
the University of Florida in Wildlife and Range Science in 1992. Her early studies and fieldwork centered on primates, writing her master's thesis on the monkeys of the
Tana River Primate National Reserve. Between undergraduate and graduate school, Kahumbu returned to Kenya to work for the
Kenya Wildlife Service. There, she was charged with counting and measuring the ivory stockpile in the country's vaults in preparation for
Richard Leakey's now-famous internationally televised burning of the tusks. The event changed her focus from primates to elephants for her doctoral work. She was granted a Petri scholarship to attend
Princeton University to complete her PhD in Ecology and Evolutionary Biology from 1994 to 2002, where she studied elephants in the
Shimba Hills on the Kenyan coast. In 2005, she received her certificate in the Program for Management Development from the Gordon Institute of Business Sciences at
the University of Pretoria. == Conservation career ==
