About me

About me

In the 1980s: field research on the behavioural ecology of western lowland gorillas at Lopé in Gabon as a Ph.D. student and then a post-doc. In the 1990s: worked in the forests of Cameroon (Dja), Central African Republic (Bangassou), Democratic Republic of Congo (Kahuzi-Biega), Liberia (Sapo) and Rwanda (Nyungwe and Volcanoes). Director of the Karisoke Research Centre in Rwanda for Dian Fossey Gorilla Fund International for six years, until 2002. Vice Chair of the Section on Great Apes (SGA) of the IUCN SSC Primate Specialist Group for 10 years to 2016. I continue to serve on the Executive Committee of the Section on Great Apes. I am the IUCN Red List Authority Coordinator for all great ape taxa: bonobos, chimpanzees, gorillas and orangutans (https://www.iucnredlist.org/assessment/authorities); co-Chair of a working group on COVID-19 and great apes (http://www.primate-sg.org/covid-19); and member of a task force that aims to "reduce and restore negative impacts from energy, extractive and associated infrastructure projects on great apes" (https://www.arrctaskforce.org).

Award

Award for Excellence in Primate Conservation
The fifth biennial Margot Marsh Biodiversity Foundation Award for Excellence in Primate Conservation was given to Liz Williamson in recognition of her achievements in gorilla conservation. The Margot Marsh Biodiversity Foundation was established in the 1990s, and has provided more than $12 million to primate conservation projects worldwide. https://www.grantmakers.io/profiles/v0/330683174-margot-marsh-biodiversity-foundation-co-first-republic-investment-management/


Research

Conservation, ecology and behaviour of gorillas (eastern and western) and other great apes. Areas of particular concern are prevention of disease transmission from humans to great apes, and limiting the negative impacts of tourism on great apes. I have edited and produced a number of IUCN publications, including conservation action plans for gorillas, chimpanzees and bonobos (http://www.primate-sg.org/action_plans); and a series of best practice guidelines for great ape conservation (http://www.primate-sg.org/best_practices).
