Professor Karen Reynolds' office at Flinders University is a place where curiosity meets real-world problem-solving. For nearly three decades, she has been shaping biomedical engineering in Australia, helping turn ideas into devices that save lives. While her work sounds high-tech, it all began with a simple fascination.
From a Career Handbook to a Pioneering Career
“I always loved medicine and the human body, but I didn’t think I wanted to be a doctor,” she says. “Then, at about 15, I saw something called biomedical engineering in a careers handbook. I thought, ‘That’s exactly what I want to do’.” At that time, biomedical engineering was barely recognised. No degrees existed, so Professor Reynolds studied physics before finding a master’s program in the field. She did not plan to become an academic, but a series of research opportunities—and a job at Flinders University in 1997—kept her in the lab. “Flinders was perfect,” she says. “We shared a campus with a teaching hospital, and it was the first university in Australia to offer an accredited biomedical engineering degree. The job description basically sounded like it was written for me.”
A Diverse Range of Projects
Reynolds’ career covers an extensive range of projects. Early work involved pulse oximeters—the small devices clipped on fingers to measure blood oxygen—and prosthetic heart valves that were failing in patients. Later, she focused on surgical tools, figuring out how to safely implant screws in bone and prevent failures in the operating theatre.
The Medical Device Partnering Program
Her talents truly shone through in the Medical Device Partnering Program, which she established in 2008. The program acts like an incubator for ideas, guiding clinicians and independent inventors through the complex process of bringing medical devices to market. “We see 60 to 100 ideas a year,” she explains. “Some are simple assistive devices, like something to help a person stand. Others are implantable electronics that need to be tightly regulated. Every day, a new idea pops up, and it’s thrilling to help it along. It’s not just about the tech—we want to make sure these ideas actually get to patients who need them.”
Beyond the Lab: Commercialisation and Impact
Helping ideas survive beyond the lab is just as important as the engineering itself. Professor Reynolds’ team advises on commercial potential, regulatory hurdles, and prototyping. One standout project is a cancer-detecting probe that measures tissue acidity to locate tumours. Technology is moving at lightning speed, with examples such as cloud connection, AI, and drug-delivering implants, but Professor Reynolds and her team navigate that complexity with optimism. “Things are more complex than ever,” she says. “But that also makes the opportunities amazing.”
Director of the Flinders Factory of the Future
That spirit of possibility now extends beyond the medical sphere. As the newly appointed Director of the Flinders Factory of the Future, Professor Reynolds leads the transdisciplinary advanced manufacturing Research Hub, where technology, engineering, and human factors come together to deliver practical, evidence-based solutions. She and her team drive productivity, reduce costs, and open new frontiers in advanced manufacturing.
Recognition and Team Spirit
Recognition has followed, with awards as Professional Engineer of the Year in 2010 and Scientist of the Year in 2012, but she says the awards reflect her team more than her. “As an academic, you’re only as good as the people you work with,” she says. “I have colleagues who bring expertise in governance, research, industry partnerships, and working with First Nations communities. Any success I’ve had is about the team, not me.” Her approach to innovation goes beyond engineering—it is about connecting people, ideas, and opportunities. “It’s not just the technical problem,” she says. “Success comes down to understanding the need, navigating the regulatory pathway, and making the right connections. Even the most brilliant idea will stall without the right support behind it. Our job is to bridge that gap—to take promising concepts and help shape them into solutions that genuinely improve lives.”
Thrill of Seeing Ideas Take Off
Even with decades of experience, Professor Reynolds says she still gets a thrill from seeing a good idea take off. “Sometimes you see a fantastic concept and it doesn’t go anywhere—not because the idea itself is bad, but because of funding constraints, or the wrong connections,” she says. “Our role is to spot those ideas early and help them along so patients can benefit.”
From heart valves to cancer probes, from surgical instruments to cutting-edge industry innovation, Professor Reynolds’ impressive body of work bridges the gap between science and impact. “Every day there’s something new,” she says. “Biomedical engineering is about problem-solving in the real world, and there’s nothing more satisfying than seeing it make a difference for someone.”
