We join many tributes across Aotearoa and globally honouring the life of Professor Alistair Gunn.
Prof Gunn’s research led to the development of therapeutic hypothermia (brain cooling after oxygen deprivation): a simple, safe and globally adopted treatment protecting newborn babies’ brains after oxygen deprivation at birth. His work continues to save countless lives and enable millions of children to grow and thrive without disability.
For us at AMRF, this legacy is deeply personal. Prof Gunn acknowledged our early support helping his team develop the first cooling machines and undertake the critical studies making this breakthrough possible. Those studies established how and when cooling could protect the newborn brain, laying the foundation for international clinical trials that followed and for a treatment now used internationally.
He once described therapeutic hypothermia as “an overnight success, after 20 years of preclinical research”—a reflection of his persistence, scientific rigour, and commitment to improving outcomes for babies and their families.
Behind his extraordinary impact was scientific brilliance, and a deeply human presence. He is remembered by colleagues globally as kind, generous, quietly determined, endlessly curious. He was known as a mentor who gave his time freely, a collaborator who lifted others, and a person whose warmth was felt in every interaction.
Tributes shared across the global research and clinical community speak to a life defined not just by achievement, but by character. He was known to be a brilliant colleague, an outstanding researcher and human being, humble and supportive, and someone whose work profoundly improved the life chances of so many. Others recall his encouragement of early-career researchers, his thoughtful questions, and genuine care he showed to those around him.
His legacy continues in clinicians who carry forward his work, researchers he inspired, and families whose lives are forever changed because of his dedication.
