The University of Melbourne’s first female vice-chancellor has died of cancer less than 12 months after taking up the post.
Professor Emma Johnston, 52, described as a talented marine ecologist and “visionary leader in science and research”, was appointed to the post in February 2025, replacing Duncan Maskell, who faced a tumultuous period when he took up the post in 2018, marred by COVID-19, pro-Palestinian protests and debates over international borders.
Survived by her husband and two children, Johnston has been described as “an optimist to the end”, having completed her resilience strategy for college, the first step of her 10-year plan, just weeks before her death.

“He was truly the leader of our time.”
