Clinician Profile


Dr Barabara Withers
Director of Haematology and Bone Marrow Transplantation

What inspired you to specialise in haematology and bone marrow transplantation?
“With a background in pharmacology and medicine, I was drawn to haematology through witnessing the profound impact of blood cancers on patients and families. My training and fellowship in bone marrow transplantation confirmed this path, and I’m proud to contribute to St Vincent’s 50-year legacy of excellence in stem cell transplantation as both a clinician and researcher.”

How has philanthropic support helped strengthen haematology and transplant services at St Vincent’s?
“Philanthropy has been foundational to everything we do, and my career has been shaped by donor generosity. I was fortunate to receive a fellowship during my PhD where I studied donor immune cells for CMV infection after transplant – research that contributed to an international award for new investigators.

Beyond individual support, philanthropy has transformed our service, funding the Haematology, Blood & Marrow Transplant Unit redevelopment, clinical trials, specialist roles, advanced equipment and expanded cellular therapies, enhancing treatment options and patient care. None of this progress would be possible without our donor community.”

What difference does access to cutting-edge transplant therapies make to patients and their families?
“These therapies change lives in the most profound ways. I’ve seen patients with aggressive blood cancers overcome extraordinarily difficult prognoses. Our autologous transplant program for Multiple Sclerosis and other neuroimmune disorders offers long-term stability without immunosuppressants, helping patients regain independence and return to work or activities they hadn’t been able to do since diagnosis. For families, this means hope, relief and a future that once seemed out of reach.”

How does investment in cellular therapies translate into better patient outcomes?
“Cellular therapies let us precisely rebuild or redirect the immune system, improving outcomes where traditional treatments fall short. Investment in this field expands clinical trials, offers safer therapies with less toxicity, develops local CAR-T manufacturing to reduce cost and delays, and explores new applications for autoimmune conditions, giving patients not just longer, but better lives.”

As we mark the 50th anniversary of Bone Marrow Transplantation at St Vincent’s, what excites you most about the future of transplant science?
“I’m really excited about how rapidly laboratory discovery is now translating into clinical care. I entered this field because I wanted to bridge that gap. My own work across bone marrow transplantation, cellular therapies and translational research reflects how closely our science and clinical
practice now interact.

To our Foundation supporters: you have genuinely shaped the course of this program. Your generosity has supported researchers, funded fellowships, enabled ward redevelopment, accelerated clinical trials and given patients access to world leading care. Our next chapter is ambitious, but with your continued partnership, it is absolutely within reach.”
