Olivia Reynolds

Team Lead - Research

Bachelor of Science with Honours, PhD Ecology

Olivia leads Cesar’s research teams. Olivia is an applied ecologist who has successfully combined her passions – wildlife, people, experiencing new cultures, and making a difference – to develop a career in sustainable pest management.

After completing her PhD, Olivia spent two years travelling widely in Europe and gaining work experience, before commencing her lifelong dream to live and work in Africa, completing a post doctorate with the South African Sugarcane Research Institute and lecturing at the University of Witwatersrand in South Africa. Prior to joining Cesar, Olivia was a Principal Research Scientist with the NSW DPI, during which she advanced her executive level leadership capabilities, graduating from the Women in Leadership Australia, Advanced Leadership Program.

Olivia values applying sustainable and ecological pest management approaches that are embraced by stakeholders. Her research interests and expertise include silicon in insect plant defences, sterile insect technique, parasitoid ecology and behaviour, biosecurity, area-wide management and landscape ecology/habitat manipulation.

Olivia is an Adjunct Associate Research Professor at Charles Sturt University, a member of the Graham Centre for Agricultural Innovation and a Jinshan Scholar at the Institute of Applied Ecology, Fujian Agriculture and Forestry University, China.

Internationally, Olivia is an Australian representative on the International Steering Committee for Fruit Flies of Economic Importance, a co-founder of the International Atomic Energy Agency/Food and Agricultural Organisation Tephritid workers of Asia, Australia and Oceania (TAAO), an Editor on the peer-reviewed journal, Insects and an Editor on the international bulletin, Fruit Fly News.

Olivia enjoys mentoring staff and students, providing an encouraging and supporting environment to enable them to reach their full potential.

When Olivia is not working, she loves travelling and exploring new destinations with her husband and two boys, hiking, reading, skiing, spending time in the garden and entertaining.
