David Gardner
He asked what an embryo meets on its way through the body, and built culture that changes with it.
A student at York. David Kenneth Gardner studied biology at the University of York, graduating in 1984. He stayed to do his PhD with Henry Leese, completing it in 1987. Together they measured the nutrients taken up by single mouse embryos without harming them, published in 1986 in the first issue of Human Reproduction. In 1990 they also reported what the fluid of the mouse oviduct contains, the first home of every embryo.
Harvard and Monash. In 1988 he became a fellow in cellular and molecular physiology at Harvard Medical School, working with John Biggers. Their 1989 paper measured how much glutamine a single mouse embryo takes up. In the late 1980s he moved to Monash University in Melbourne to work with Alan Trounson. There, with Michelle Lane and clinical colleagues, he analysed fluids from the human oviduct and uterus. The early embryo and the later blastocyst meet different fluids, and have different needs. Gardner and Lane argued that culture should change in two steps to match. This approach became known as sequential media.
Day five in Denver. In 1997 he became Scientific Director of the Colorado Center for Reproductive Medicine, working with William Schoolcraft until 2007. Their 1998 paper showed that growing embryos to the blastocyst stage raised the chance of each one implanting, so fewer needed to be transferred. With Schoolcraft he described a grading system that gives each blastocyst a number and two letters, such as “4AA”. In 2000 they showed that this score was linked to implantation and pregnancy, a step towards transferring a single blastocyst.
Back to Australia. In 2007 he returned to Melbourne as Professor of Zoology at the University of Melbourne. He was Head of the Department of Zoology from 2009 to 2014 and has been a Research Professor in the School of BioSciences since 2015. His work looks at how diet, environment and culture conditions affect gametes, embryos and the health of the children they become.
Honours. He was elected a Fellow of the Australian Academy of Science in 2017. In 2022 he was appointed a Member of the Order of Australia for significant service to reproductive medicine and to education. In 2026, forty years after their first paper together, he and Henry Leese wrote again in Human Reproduction, teacher and student still side by side.
