Evatt Chirgwin

Research Scientist

Bachelor of Science with Honours (Ecology and Evolutionary Biology), PhD Evolutionary Biology and Climate Change

Evatt is captivated by how animal and plant populations adaptively evolve to overcome the challenges posed by their environment. At Cesar, he investigates how pest species evolve resistance to pesticides and other management practices so these species can be controlled by the agricultural industry in the most effective and sustainable way.

Growing up on the Mornington Peninsula, Evatt was always curious about the diversity of life that surrounded him—from the tiny intertidal rock pools to the expansive eucalypt forests. This curiosity eventually led him to undertake a PhD at Monash University where he used quantitative genetics to explore the potential of marine invertebrate populations to adaptively evolve under future levels of ocean warming. He is also actively interested in making scientific research more broadly accessible, which has led him to work with organisations such as Remember the Wild to educate the broader community about biodiversity in their local area.

Outside of work, Evatt loves spending his time hiking and searching for new dive spots along the Victorian coast.
