Samantha Ward

Research Scientist

Bachelor of Science (Zoology), Master of Science (Environmental Management), PhD (Agricultural entomology)

Sam joined the Cesar Australia team to manage the green peach aphid (GPA) work and use her expertise in taxonomy to contribute to a range of Cesar Australia projects.

In Wales, Sam received a first degree in BSc Zoology studying garden snails. She received industry funding to undertake an MSc in Environmental Management, investigating the effects of woodland conservation on arthropods. After spending a few years travelling around the globe and volunteering at the Natural History Museum in London, UK, working on parasitoid wasp taxonomy, Sam decided to return to study. At the University of Melbourne, she began a PhD on the topic of using parasitoid wasps to control grain aphids in 2016. A highlight of Sam’s career was naming a species of parasitoid wasp after her father; ‘Eretmocerus garrywardi’.

Sam is passionate about food security, habitat management and the adoption of beneficial invertebrates within integrated pest management strategies. As the editor of the Australian Entomological Society’s newsletter, Myrmecia, she is at the forefront of entomological news.

When not at work, Sam can be found adventuring around Australia or other parts of the world, looking for animals at all times of the day! She is a scuba diver instructor and enjoys reading crime novels.
