Dr. Sally Shrapnel: From General Practitioner to Leading Quantum Scientist

Dr. Sally Shrapnel has emerged as one of Australia’s foremost quantum scientists after a remarkable transition from a 20-year career as a general practitioner. This journey began when she decided to pursue her childhood ambition of delving into the world of physics, ultimately leading her to the University of Queensland, where she currently serves as an associate professor.

Dr. Shrapnel’s fascination with science was ignited in her youth, fueled by a childhood filled with science fiction literature. She cites John Wyndham’s 1960 novel, "Trouble with Lichen," which featured a female biochemist, as a pivotal influence that inspired her early interest in science. “I’ve always been fascinated by really, kind of, outrageous science ideas,” Dr. Shrapnel remarked.

After completing her Bachelor of Medicine and Bachelor of Surgery at the University of Queensland in 1995, Dr. Shrapnel initially aspired to become a radiologist. However, her experience as a general practitioner in various locations, including Tasmania and the United Kingdom, led her to develop a passion for the technical aspects of science. This realization prompted her to return to academia in her early 40s, enrolling in a diploma in philosophy at the same university, where she began to question the foundations of scientific explanations, particularly in quantum theory.

Dr. Shrapnel’s academic pursuits culminated in a PhD focused on quantum theory, which she describes as “the most fundamental theory…the physical theory of how the world works.” Her research now explores the intersection of quantum principles with artificial intelligence (AI) and machine learning, developing new algorithms that could enhance healthcare decision-making and other applications.

This year marks the centenary of the quantum revolution, an event underscored by the United Nations’ declaration of 2025 as the International Year of Quantum Science and Technology. Dr. Shrapnel emphasizes the importance of quantum technology, which powers smartphones, medical imaging, and various industrial applications.

Until recently, Dr. Shrapnel served as the deputy director of the Australian Research Council (ARC) Centre of Excellence for Engineered Quantum Systems (EQUS), a program that concluded in May 2025 after 14 years of funding. Under her leadership, EQUS became a prominent force in quantum science, connecting researchers from multiple leading Australian universities and facilitating the establishment of several startups, including Iceberg Quantum and Redback Systems.

Dr. Shrapnel describes Australia as a “quiet achiever” in quantum science, asserting that the country has significantly contributed to the global quantum landscape. “Australia just punches way above its weight in terms of quantum science,” she stated. The centre’s legacy continues through its alumni, many of whom have taken on influential roles in quantum research and entrepreneurship.

Looking forward, Dr. Shrapnel aims to inspire future generations of scientists, particularly women, to pursue careers in physics. Despite the challenges associated with quantum science, she characterizes it as the “most exciting and interesting area of science that you can work in.” Her diverse background, combined with her passion for science, positions her as a role model for aspiring scientists worldwide. As she puts it, she is now living the life she had once only read about, blending scientific inquiry with imaginative exploration.
