Anthony van Rooyen

Research Scientist (Genetics)

Bachelor of Science with Honours (Biochemistry)

Anthony van Rooyen provides critical genetic analysis, research and innovation at Cesar Australia. His portfolio includes projects on animal health, biosecurity, monitoring, genetic rescue and insect pest management. He loves that his work involves a wide variety of projects, which has meant that he has been able to get out in the field and apply technology to many different areas.

While Anthony has a broad skillset and knowledge of contemporary genetics, his real skill is in applying these genetic “toolkits” for positive outcomes in sustainability and conservation. He likes to do this by working with clients and researchers from a diverse range of disciplines, and will always spend time with them first get a thorough understanding of their needs.

Anthony grew up on a picturesque farm nestled between the Pacific Ocean and the Southern alps which nurtured a strong interest for agriculture and environment. This led him to Lincoln University, Canterbury where he achieved First Class Honours in Biochemistry. Prior to joining cesar he was part of a research team investigating the effects of ocean acidification on seafloor ecosystems in Antarctica, although, by being based in temperature/pH controlled labs in New Zealand he missed out on those Antarctic conditions.
