At age 12, Gladys Kalema-Zikusoka founded a wildlife club at her school in Kampala, initiating a lifelong commitment to animal conservation. By 1996, at age 25, she became the first wildlife veterinary officer for the Ugandan Wildlife Service, tasked with protecting the Bwindi mountain gorilla population, which then numbered approximately 300 individuals.
Veterinary Foundation and Research
Kalema-Zikusoka pursued professional veterinary training through studies at the University of London Royal Veterinary College, where she earned a Bachelor of Veterinary Medicine. She later obtained a Master of Veterinary Medicine from North Carolina State University in 2003, followed by a Master of Business Administration in 2016 and a certificate in non-profit management from Duke University. Her early field research identified that parasite transmission from humans to mountain gorillas posed a critical survival risk. This discovery highlighted the necessity of managing human disease to prevent the potential extinction of these primates.

In 2003, Kalema-Zikusoka co-founded Conservation Through Public Health (CTPH) alongside Lawrence Zikusoka and Stephen Rubanga. As CEO, she directed the organization to address the interplay between ecological health and local human communities. The CTPH model integrates wildlife protection with initiatives such as expanding local access to family planning and improving communication infrastructure. In 2015, the organization launched Gorilla Conservation Coffee, a program designed to assist local farmers in achieving international market prices for Arabica crops. By increasing household incomes, the initiative reduces the economic necessity for activities that heighten disease transmission risks between residents and the gorilla population.
Public Policy and Recognition
Throughout her career, Kalema-Zikusoka pioneered translocation strategies to restock national parks following poaching incidents during Uganda's civil wars. Her efforts contributed to a demographic shift, with Bwindi gorilla numbers rising to approximately 460 by 2018, leading to a status reclassification from critically endangered to endangered. The international community has honored her contributions with several awards, including the 2009 Whitley Gold Award, the 2018 Sierra Club EarthCare Award, and the 2022 Edinburgh Medal. In 2021, the United Nations Environment Programme named her a Champion of the Earth for Science and Innovation.
