Dr Olivia Reynolds (née Kvedaras) is the Research Lead, cesar based in Melbourne. Previously, Dr Reynolds was a Principal Research Scientist based at the Elizabeth Macarthur Agricultural Institute near Sydney.

Olivia completed a postdoctoral fellowship in 2006 with the University of Witwatersrand and the South African Sugarcane Research Institute and a PhD in 2002 with the University of New Englan

Olivia’s research themes include landscape ecology/area wide integrated pest management, fruit fly management and silicon-based plant defence. Olivia applies ecological knowledge to elucidate pest problems through the development and implementation of sustainable, low environmental impact approaches that are both relevant to the wider research community and embraced by applicable stakeholders, including growers. For example, the development of novel means (e.g. semiochemical, probiotic) by which to enhance fitness and performance of sterile male Queensland fruit fly (Qfly).

Olivia collaborates broadly, both nationally and internationally. This includes her current posts as a Jinshan Scholar with Fujian Agricultural and Forestry University, and an Adjunct Associate Research Professor with Charles Sturt University.  Olivia also recently advanced her executive level leadership capabilities, graduating the Women in Leadership Australia, Advanced Leadership Program with the Macquarie School of Graduate Management.
