Emma Johnston's Remarkable Journey from Marine Ecologist to University Leader

Professor Emma Letitia Johnston AO, born on June 11, 1973, in Melbourne, grew up in the seaside suburb of Williamstown, where her passion for the ocean was ignited through swimming, snorkelling, and sailing. Her father, an applied mathematician, and her mother, a painter with a chemistry background, fostered an environment rich in intellectual curiosity. She attended University High School before pursuing a Bachelor of Science with first-class honours at the University of Melbourne in 1998, followed by a PhD in marine ecology in 2002. Her doctoral thesis, supervised by Mick Keough, examined the effects of transient copper pollution on marine epifaunal assemblages.

Johnston's academic career began at the University of New South Wales (UNSW Sydney) in 2001 as an associate lecturer. She quickly rose through the ranks, heading the Applied Marine and Estuarine Ecology Lab and becoming inaugural director of the Sydney Harbour Research Program in 2012. Her leadership extended to Pro Vice-Chancellor (Research) and Dean of Science at UNSW, before serving as Deputy Vice-Chancellor (Research) at the University of Sydney from 2022. In February 2025, she returned to her alma mater as the 21st and first female Vice-Chancellor of the University of Melbourne, a role she held until her untimely passing.

Groundbreaking Research in Marine Ecology and Environmental Science

Johnston specialized in the ecological impacts of human activities on marine ecosystems, blending ecology, microbiology, and ecotoxicology. Her research spanned Sydney Harbour, Antarctica, the Great Barrier Reef (GBR), and Australian estuaries, revealing how toxic contaminants facilitate invasive species and identifying drivers of marine bio-invasions. She authored 185 peer-reviewed journal articles, achieving an h-index of 65, and supervised over 35 higher degree by research students.

Key contributions included pioneering biomonitoring techniques and informing biodiversity management. As a chief author of Australia's State of the Environment Report and a director of the CSIRO and GBR Marine Park Authority, her work underscored ecosystem resilience amid pollution and climate change. Johnston's advocacy extended to public communication; she co-presented Coast Australia and appeared on ABC's Catalyst, earning the 2015 Eureka Prize for Promoting Understanding of Australian Science.

Trailblazing Leadership Roles Across Australian Universities

Johnston's ascent in higher education leadership was meteoric. At UNSW, as Dean of Science, she prioritized family alongside career, negotiating flexible commitments. Her roles at the University of Sydney involved institution-wide reforms, showcasing her ability to navigate complex academic environments. As president of Science & Technology Australia, she launched the Superstars of STEM program to elevate women and non-binary scientists.

Her awards reflect this impact: Officer of the Order of Australia (AO) in 2018, Fellow of the Australian Academy of Science (2022), Nancy Millis Medal (2014), and more. These honors recognized her service to higher education, marine ecology, and scientific institutes. Johnston's style—optimistic, collaborative, and student-focused—redefined leadership in Australia's Group of Eight universities.

• Established Sydney Harbour Research Program, integrating industry and government collaboration.
• Advocated for gender equity, mentoring countless women in STEM.
• Served on boards like CSIRO and Ian Potter Foundation, bridging research and policy.

Her Brief but Transformative Tenure at the University of Melbourne

Appointed in February 2025, Johnston's 11-month tenure as Vice-Chancellor was marked by energy and vision. She launched the Resilience strategy, a cornerstone of a 10-year plan to empower Australia's future through academic excellence. Despite her illness, she addressed student cost-of-living pressures, expanded scholarships, and enhanced teaching and research support, often engaging directly with students to hear their stories.

Chancellor Jane Hansen AO noted: "Professor Johnston brought a tone of optimism and energy... her belief in all who are part of this community." Her focus on science communication promoted women in STEM and marine conservation.University of Melbourne Leadership Profile

Outpouring of Tributes from the Higher Education Community

News of Johnston's passing on December 26, 2025, due to cancer complications, prompted widespread grief. The University of Melbourne's condolence book overflowed with messages praising her charisma and optimism. Federal Education Minister Jason Clare called her "one of Australia's biggest brains and nicest people." Victorian Premier Jacinta Allan highlighted her as a mentor showing "what was possible for women in science."

University of Sydney VC Mark Scott deemed her "destined to be a vice-chancellor," while Universities Australia Chair Carolyn Evans lauded her as an "extraordinary scientist." Tributes from UNSW, ANU, and Group of Eight underscored her sector-wide influence.ABC News CoverageThe Conversation Tribute

Advocacy for Women and Diversity in Australian Higher Education

Johnston was a fierce advocate for gender equity. Programs like Superstars of STEM and her board roles amplified women in research. As GBRMPA Chair Ian Poiner noted, she championed stewardship and equity "in and out of the water." Her mentorship empowered early-career researchers, particularly women, aligning with her vision for a resilient academic workforce.

In Australia, where women hold only 30% of senior academic roles (per government data), Johnston's example as UniMelb's first female VC inspired change. Explore career advice for research assistants to follow in her footsteps.

The Professor Emma Johnston Fund: Perpetuating Her Legacy

Johnston's family established the Professor Emma Johnston Fund via Australian Communities Foundation, focusing on early-career women researchers, time-critical marine studies post-catastrophes, and science communication. Tax-deductible donations ensure her commitment to marine ecology endures.

• Support for women early-career researchers (ECRs).
• Funding urgent responses to environmental disasters.
• Promoting effective science outreach.

University of Melbourne's Path Forward Under Interim Leadership

Following Johnston's death, Professor Michael Wesley initially acted as Vice-Chancellor. In January 2026, Emeritus Professor Glyn Davis AC, a former VC and Prime Minister's adviser, was appointed interim leader to ensure stability amid the Resilience rollout. This transition highlights Australian universities' resilience, a theme central to Johnston's vision.
