Indian-origin mathematician Nalini Joshi named NSW Scientist of the Year 2025

Indian-origin mathematician Prof Nalini Joshi AO has been named the 2025 New South Wales Scientist of the Year, marking the first time a mathematician has received the state’s top science honor, officials announced in Sydney.

The award was presented at the NSW Premier’s Prizes for Science and Engineering ceremony held at Government House.

Prof Joshi, who teaches applied mathematics at the University of Sydney, was recognized for her far-reaching contributions to mathematical sciences and their real-world applications.

Her research has played a key role in improving scientific understanding of complex systems, including the behavior of light in optical fibers and the formation of rare and unpredictable rogue waves in deep oceans.

These studies have implications for climate research, communications technology, and related fields. The NSW Scientist of the Year title includes a trophy and a cash prize of $60,000.

Officials said the recognition highlights the growing importance of mathematics in addressing scientific and technological challenges.

Joshi’s achievement has also drawn international attention. The Australian High Commission in India acknowledged the honor on social media, noting her role in strengthening global scientific collaboration and celebrating her Indian-origin background.

Beyond applied mathematics, Joshi’s work extends to quantum technology and cybersecurity.

She has emphasized the need for new mathematical frameworks, as advances in quantum computing could eventually undermine existing digital security systems.

At the ceremony, NSW Premier Chris Minns praised her contributions, saying her work helps “make sense of nature’s big mysteries” while encouraging the next generation of scientists.

Accepting the award, Joshi said she was “deeply honored and humbled” and encouraged young people not to fear mathematics, describing it as a powerful tool for understanding the universe.

In addition to her research, Joshi is known for advocating gender equity in science. She co-founded the Science in Australia Gender Equity program, which focuses on improving participation and retention of women in science and mathematics.

Alongside Joshi, nine other researchers and innovators were honored across categories such as biological sciences, engineering, and early-career research, reflecting the depth of scientific work being carried out across New South Wales.
