In a landmark moment for the mathematical sciences, Professor Nalini Joshi AO, an Indian-origin academic and one of Australia’s most respected applied mathematicians, has been named the 2025 New South Wales (NSW) Scientist of the Year, becoming the first mathematician to receive the state’s highest scientific honour.
The recognition was announced at the NSW Premier’s Prizes for Science & Engineering ceremony held at Government House in Sydney, placing Joshi among Australia’s most influential scientific leaders and drawing renewed global attention to the role of mathematics in solving real-world challenges.
The award, which includes a trophy and a AUD 60,000 cash prize, acknowledges Professor Joshi’s transformative contributions to applied mathematics and her impact across fields ranging from climate science and communications to quantum technology and cybersecurity.
A Rare Honour for Mathematics
While scientists from disciplines such as biology, medicine, and engineering have traditionally dominated top-tier science awards, Joshi’s selection marks a significant shift. Her recognition underscores the growing understanding that mathematics is not an abstract pursuit, but a foundational discipline driving innovation across modern science and technology.
“This is a milestone moment not just for me, but for mathematics as a discipline,” Joshi said at the ceremony. She described herself as “deeply honoured and humbled” by the recognition, and encouraged young people to approach mathematics with curiosity rather than fear.
“Maths should not be intimidating,” she said. “It is one of the most powerful tools we have for understanding the universe and solving problems at every scale.”
Global Impact of Her Research
Professor Joshi is a leading figure in applied mathematics at the University of Sydney, where her research has advanced global understanding of complex systems—systems in which small changes can produce large and often unpredictable effects.
Her work has helped explain how light propagates through optical fibres, research that has direct implications for high-speed communications and data transmission. She has also contributed to the mathematical modelling of rogue waves, massive and unpredictable ocean waves that pose serious risks to ships, offshore platforms, and coastal infrastructure.
Scientists note that understanding such phenomena has far-reaching consequences, from climate modelling and marine safety to engineering design.
“Professor Joshi’s work helps make sense of nature’s big mysteries,” NSW Premier Chris Minns said while presenting the award. He praised her ability to connect deep theoretical insight with practical scientific application, adding that her career serves as an inspiration for future generations of researchers.
Beyond Academia: Quantum and Cybersecurity Frontiers
Joshi’s influence extends well beyond traditional academic boundaries. Her research increasingly intersects with quantum technology, an area expected to reshape computing, encryption, and national security.
She has highlighted the urgency of developing new mathematical frameworks as quantum computers grow more powerful—potentially threatening today’s digital security systems.
“Quantum technologies will demand entirely new ways of thinking about security,” Joshi has noted in academic forums. Her work helps lay the mathematical foundations needed to anticipate and address these future risks, positioning mathematics at the heart of next-generation cybersecurity.
Championing Gender Equity in STEM
In addition to her scientific achievements, Professor Joshi is widely respected for her leadership in advancing gender equity in science, technology, engineering, and mathematics (STEM).
She is a co-founder of the Science in Australia Gender Equity (SAGE) program, a national initiative designed to increase the participation, retention, and advancement of women in scientific and mathematical careers. The program has played a critical role in reshaping institutional policies and cultures across Australian universities and research organisations.
Colleagues describe Joshi as a mentor who has consistently used her platform to open doors for others. “Her impact is not just measured in equations and publications, but in people,” one academic peer said.
International Recognition
Joshi’s achievement has resonated beyond Australia. The Australian High Commission in India highlighted her honour on social media, celebrating her as an example of the global contributions made by Indian-origin academics and the enduring links between India and Australia in science and education.
Her recognition comes at a time when international collaboration in science is increasingly vital, particularly in areas such as climate change, digital security, and advanced technology.
Celebrating NSW’s Scientific Excellence
Alongside Joshi, nine other scientists and innovators were recognised across categories including biological sciences, engineering, and early-career research. Together, the awards showcased the depth and diversity of scientific talent in New South Wales.
Yet Joshi’s historic win stood out—not only for breaking disciplinary barriers, but for reinforcing a broader message: that mathematics lies at the core of understanding, innovation, and progress in an increasingly complex world.
